Sman3 question

[knave]

I want to buy the sman3's but I do sometimes get caught in the rain while charging. I haven't heard anything about how weatherproof they are.

I want to buy the sman3's but I do sometimes get caught in the rain while charging. I haven't heard anything about how weatherproof they are.

Don't think they are waterproof... I know the digi cools can be put in a sink!:grin2:

Also the FP is having manifold issues..


Can someone help me on this question that has been bugging me. IF your a member of this forum most likely everyone knows that the Digi's are the best. But people still spring for a POS and come here later and complain that the thing doesn't work. (Note: OP that was not directed to you) Why not just buy what we all have tested and know works??

[10phaseadapter]

i have no issues with my sman, yet atleast. i really love the thing to be honest.

to OP if im caught out in the rain charging, ill just throw the jacket it comes with on, turn the back light on and take a peak from under neath.

[ptemko]

Why not just buy what we all have tested and know works??

I started out with the Digi cools 1200 clamp wire broke the first week I had it after many repairs I stopped using the clamp. Bought the Testo 550 never had a problem with it yet. I saw the Sman3 and thought what the heck and picked one up to test it out. Have been using it everyday since I got it about 2 months ago. The high side clamp broke on me Friday. I have since pulled the Digi cool apart and cut the plug adpter out and installed my own wires and plug. Using a set up I bought from Radio shack. Looks like a stereo head phone jack mini style. So I am sure it does not matter which ones people buy there will always be something come up that is wrong.

good point. Here's my reason.

The manifold that I have now, I would like to keep intact as a backup. IOW If I bought digicool, I would need to buy new manifold and hoses.

I like the idea of choosing my manifold.... but 1250's plus manifold and hoses = too much moola

[ptemko]

I have my 1200 Digi cools sitting on the Brute 4 valve manifold with yellow jacket 1/4 turn style hoses. Been using them on and off for a couple of years. Just installed new valve seats this morning for the heck of it. Good as new

Ok, hear me out. Maybe I'm crazy and if I am please say so. This is my thinking..

So lets say you buy the $300.00 manifold. You use them for a 6 months and have problems with them. You say the hell with this, Let my try these dig's that everyone has been raving about. Now you spent 300.00 for a paper weight and that brings you up to a total of $900.00!! Now that is too much moola if you ask me.
Plus with dig's you don't have to buy a new manifold. Use what you got. YOu won't need a back up because they just work. SO there you have it.. BTW that first paragraph happened to one of my buddies. I still say " I told you so" lol.

Buy it once dude. Save up for the Best. Look on this forum, There are far more Problems with the other Brands out there. I mean do what you want. This is my opinion. Ive spent a lot of extra money doing what your talking about right now and it pisses me off that I have leak detectors and micron gauge paper weights sitting in my garage.I can't throw them out because the were about $200 bucks. But if I would have spent the extra $$ I would have saved frustration and money. Hell I could have 2 digs for the money I spent on the JUNK:gah::gah:

[acguytx]

speaking of which has the new digi aks been tested proven and released in the field full time yet?

Ptemko is correct they all have issues but the Digis 1250s do seem like the best ive used especially since ive also made the mods to the temp probes the same way as described here and ever since they have been bullet proof..

however i rotate using them and my 550s and like them both the digis for mostly 410 and the 550s for mostly r22... the 550s only issues of late with hard core usage over two years is the damn clamp probes go out like no tomorrow... i need another one now.. been through about 5 now already .. if i can find a Mod for those id be in lala land..

I agree with you dude... Buy it once, buy it right....

That's why I started this thread... FP has some very quality equipment out there, backed by five star customer service... I think maybe we have a contender here lol!

But if it can't take the rain, i'll get Digicool. You never know when our tools will get doused.

You do what you can, but stuff happens..

Russell and the guys at fieldpiece are top notch when it comes to service. They're presence her shows that and I really give them a thumbs up!

I felt the same way as you with their Service and was going To buy their infrared leak detector. I decided to go with the d Tek for a couple reasons. One they're in stock locally ( I needed it) 2: talking to the guys at the supply houses they have not had many issues. Or so they say.
I honestly did not want to take a chance with the FP stuff. I have never heard anythig bad about their leak detctor but have heard plenty about the other stuff. I mean the are priced very well but that has to sacrifice something, right?
Good luck and let us know what you go with.

hey hey hey, Just cause i bought digis doesn't me you told me so, my 550's still work....:spitball:

[allenb2626]

mine has got some rain on it and worked great...just the dang high side valve grr

ok Sman and Testo guys. What do you think about this?:grin2::angel:

[Keith73]

Good, looks like an upgrade. Just seen the beta AK900, may be waiting for that to come out.

[martyinlincoln]

I want to buy the sman3's but I do sometimes get caught in the rain while charging. I haven't heard anything about how weatherproof they are.

Mine have been showered on a few times with no issues. If looks like it's going to come down hard I grab a clear plastic bag off of a media filter and stick the manifold in that.

[Rcb2875]

I want to buy the sman3's but I do sometimes get caught in the rain while charging. I haven't heard anything about how weatherproof they are.

One of the guys from FP answered this question on another thread. Went something like: Water resistant (rain) yes.. can you throw them in a pool NO.

Mine have been rained on with no problems, though I usually don't like to test the waters with them ;)

[meoberry]

Question? I just returned my sman today it started turning itself off early this morning then all of a sudden it turned off and would not come back on. There is an engineer some where whose ears are burning, I will not mention all the names I called him after I went down 16 floors, 200 yards to my truck for old reliable 18 year old yellow jackets. Then back 200 yards up 16 floors to complete charge of one pound of freon. Sman was one week old. Then found out that one of the other techs had the same problem. But he took his back for a refund. Which is what I will do if new one fails. I cannot have a tool that works when it wants to. I am extremely dissapointed with fieldpiece right now. I have always been able to count on their tools before.:mad: Has anybody else had this problem?

Not yet but OMG don't jinx me! FFS:gah: I did have one glitch when the unit was left in my truck all day sealed up. The temp was scalding hot in there when I had to get them out. The display fluttered a few times when I turned it on but was normal after a few seconds.. no problems since.

I better not hear that they cannot be stored in a hot environment or somebody is going to be wearing this thing over their head. After what I laid out for this thing. Anybody know where fieldpieces main office is located at. Just in case.........:beat:

We are located in Anaheim, CA. We will not leave you hanging on this and will get you taken care of.

I honestly have not heard of the issue you described.

All LCD's will black out at some point if the temperature gets hot enough. The higher graded LCD's will last longer..The ones on the SMAN are the high grade ones so they can withstand higher and lower temperatures than most LCDs.

If you give us a call, we will be sure to take care of you. Ask for Russ or Travis.

[itsiceman]

There was a similar complaint like meoberry posted I read here but I don't think it ever went further than that.
Not sure what happened to his.

[itsiceman]

So I"ve had my SMAN3 for a few months now. It generally does a good job but here's the glitch.

After I had used it only about 3 times, the display suddenly went blank. Well, it had the batteries in it that were shipped with the unit so I just replaced the batteries. All seemed to work. Then with the new bats in, it blinked off after about 10-minutes. Okay, I'm thinking auto-off function. So we (was working with another tech that day) restarted the unit and it blinked off immediately. Then reset again and it stayed on.

Alls been well for several weeks but the other day I removed each of the manifold adapters as there were some minor leaks around the threads. Resealed and reinstalled. Good. I made sure the gauges were turned off and returned them to my truck. On the next job, yesterday, I pulled out the gauges, pushed the 'on' button = nothing. Pushed and held the 'on' button several times = nothing. Damn. Needs batteries???? Those aren't that old but maybe the auto-off didn't work and I forgot to turn them off before I put them back in the truck??? So out come the old analogs, do the job and then stop for bats. Put in 6 brand new Duracells (this can get expensive at 6 per pop). Turn the gauges on and the display comes right up. Put gauges back in the truck.

Okay so today, first job, new batteries installed, moved the lines from the old analogs to the SMAN3 and head for the condenser. Hook up high side and turn the gauges on = nada, zilch, nothing. So in disgust, I remove the high side gauge from the manifold (I've got ball valves on the line set) and head for the truck. But I did push the 'on/off' button one more time and low and behold, the gauges came alive. So I did the job using the SMAN3 but there's definitely a problem of some sort. I think I've been replacing batteries thinking they were dead when all the time it's a fault in the manifold electronics.

Anybody else having this issue? Any solutions? Comments? :anyone:

OK! I am going to hold your feet to the fire on this. The supply house already replaced the manifold. Have not used them yet. Everything to day was chilled water units. I will let you know if the new set acts up. It has to be a connection problem somewhere in the unit. I could bump it and it would come on bump it again and it would go off. I would get it on then hang them where they would not vibrate but they would still go blank after a couple of minutes until it finally would not come on at all. I have cooled of a little about it today.

[biggi]

so i got my sman3 last week. i'm very happy with it. makes life in the field a tad easier. however i got to my last job today took the temp clamp to my low side hooked it on and it fell right off. the clamp broke right at the hinge keep in mind i just spend a pretty penny on these and i have never been this carefull with a tool.hooked it on 3/4 inch line. it just boggles me why they would break that easy. is that covered under warranty or am i just screwed.

We had a bad batch of poly carbonate clamps make it out to the field that turned out to be brittle. We fixed the problem.

Send me your address and ill take care of you and get you back up and running fast!

i had this same problem with the 2 clamps shipped with my SMAN. I contacted Russ and he sent me new ones no charge.

also they are sending me they new manifold upgrade, which will resolve the thread/ gasket issue some have complained about. Again at NO charge.

I haven't had any issue with my LCD going off, it only shuts off after the 5/10 min period. Still have the same batteries in it that it came with too! It's been about 3.5-4 months with them and i use them close to 6 times a day.

To any one with any issues just contact field piece, they will take care of you. Top shelf customer support.

I'll be glad to test my Sman3 if ever rains again in south Texas. No rain all summer long 100 degrees + everyday.

[biggi]

ok i posted my little problem with my clamps on my SMAN3 on the 16th. travis took charge and i have in my hand two brand new thermocouples today from UPS. Customer service from travis is hands down second to none. also received a set of valves with them just to up grade my unit. i didn't ask for them he just made sure i was taking care before i had an issue. THANKS TRAVIS!!!

[itsiceman]

Does the new valve flow better or was it just modified a little to stop the zero flow issue?

[Vettgetsmwet04]

The new valve holds the teflon seal very tight, do it doesn't come out and stop flow, flow is the same.

[RussellHarju]

We recently had a few technicians report a problem with high side valve on SMAN2 or SMAN3. We redesigned the valve piston to eliminate this potential problem and have incorporated this design in all SMANs shipped on or after August 15.

If you already own a SMAN, we want to make sure that you have the opportunity to get the latest valve pistons for your SMAN.

If you have an SMAN with a serial number lower than 11009403 we will be glad to send you two new valve pistons incorporating the latest design. You have two options. Email me your address and I will send a set of new valve pistons and a set of instructions free of charge so you can install them yourself at your convenience. It is a quick swap out and only requires a 15mm or 18mm wrench and about 5 minutes. Or you can ship your whole SMAN to Fieldpiece and we can replace them here and ship your SMAN back to you.

Thank you everyone for your continued support, feedback and business. Let me know if you any questions.

Working on some changes to the manifolds and the final QCing to the 900s.....I notice here some problems with PolyCarbonate......you CAN'T use straight PC with refrgt oils......or they crumble into little pieces in a few months......
Our proprietary blend of plastics took me 3 years to perfect.....oil and bullet proof....

Problem is all the big wholesalers are afraid to carry my product so my reefer company has to pay for all of this.....and I haven't embarked on a patent defense suit (yet) after having it's challenge held up in Canada and the USA....another $50,000 down the drain....
Remember, I'm a 3-4 man reefer company....not a big boy...I do this for the passion of my trade and the betterment of it/you....hopefully....and average 80-90 hours a week....between the two.

meh.. can't blame a guy for trying right!? ;) Wish the best on rolling out the new unit and sooner or later the big wholesalers will either carry your brand or just lose out on a sale. I am happy with my SMAN3 set and the level of customer service they provide but I hear the same of your products and support on here as well. I plan on ordering another SMAN3 later for next summer and may throw in an AK900 or 1250 just for variety. Any ball park figures on how much the AK may retail for?

Sounds good. Just to be clear, will the manifolds be released separately from the Ak's?

Interesting about the Polycarbonate vs. the refer oils...

I am going to make a prediction here.

If the AK900 is what I hear it is...

Keep in mind that the tech's on H-talk are some of the most well-equipped, with tools and with knowledge.... and have more than a little influence within the companies they work for/own....

My prediction is that the supply house problem will go away within 6 -12 mo. after the AK900 is released....

We've ripped apart quite a few other manufacturer's units and it's disturbing how many of them use "open" transducers where the silicone die is exposed directly to the refgt/oil/acid along with the connecting wires. There is also no or poor temperature compensation on the sensor itself.
We are getting back the crops that we sowed a decade ago by trying to get a Cadillac but only investing/paying for an Asian knock off.

We'll have a sub $300 c/w a ball valve manifold for our well known Digi-Cool quality. We'll not have a micron gauge built in as all of you know in the industry that vacuum reacts totally differently in a system and her micron gauge should be as far from the vacuum pump as possible.

Does any body know if they make a bigger clamp for the sman 3. I work with larger equipment. Need one that will fit up to a 2 inch suction line without setting me back a days pay.:lilhelp:

Use a backup temp sensor to check against as the thermocouples are notorious (obviously) for taking errant voltages right of the copper pipes (static etc) and thus combining the voltages for a false reading. This is not to mention the fact that should you get a whack of static electricity hitting the 'bead' .... it has a direct conduit right into the PCB electronics to where it can either blow it and/or whack the operator.....that's why DC and Testo don't use TCs.... ;)

[Rcb2875]

lol Not to mention they can lose themselves in a tool bag real quick! The clamp will be a lot easier to keep up with. I hate fooling with the velcro strap. I picked up a cheap little plastic clamp at the hardware store with the rubber tips and glued a piece of the stiff pipe insulation on the end so I could clamp the bead TC to the pipes and not have to steal an ATC1 from the SMAN. ;) Largest line I have to deal with is only 1 1/8".

That explains the crazy readings I was getting the other day. I switched from bead to old pocket thermometer almost throwed bead away but checked air temp and it was reading true. Good advice, thanks.:cheers:

For what it's worth Doug I put some pressure on the boys in nanaimo (Wwg) last week for not carrying your product! I'll be meeting with the regional manager next week will do the same....

Emailed Russ last night and he replied this morning to let me know new valves for my Sman 3 were in the mail.
What better service can you get.

[Petie]

Hay Russell,
Does Fieldpiece plan on a four valve version of the SMAN3 and for that matter a wireless version since they seem to be moving in that direction with their accessory heads?
Thanks

My apprentice had a 575VAC unit last week that dropped a phase and the we suspected the load side of the contactor on that phase was bleeding to ground.....on a 575 VAC "Y" system that meant that we had somewhere around 300 VAC 'bleeding' to ground.....
That means the copper pipes IF they were a poorer ground than YOU would have meant you 'bled' the power through you/the TC and the meter.....
That's why a thermistor IMHO is better and safer.....

Doug you know if the new grounded thermistor temperature sensors from testo would give a unrestricted electrical path across the meter?

It shouldn't if the sensor is isolated physically/electrically inside the sensor.
Ours is inside the barrel and the thermistor is it a glass or epoxy bead???

I guess there is a wire connected to the metal barrel of the sensors that takes the place of the manifold grounding wire they used to have so I was assuming path was thru the manifold.

The testo is not an unrestricted path, it has a large bleed resistor incorporated to bleed of any stray voltages. You can measure it if you place a meter lead on the barrel and the meter body.

Thats good news.
