Unless it is 100° where you are, that 200psi standing points to non-condensables......Just a thought.

For the record, the DM2 is still working great...........

Let it lay Doug. I have plenty of happiness. You my friend are the bitter one.:grin2:

You need to get past the me drinking thing. Calling me an alcoholic and several
other things on your other Pet forum got you nothing there, and it will get you nothing
here. Get over yourself Doug.

I have had the same thing happen with Sperry and Simpson.......Get over it.

Well, Dougy, I tried working with you and bringing your product to Texas, but you
thru one of your famous fits and that went bye-bye. Now all you can do is call me out
by my name in an open forum....

AK-900 sensor lasted exactly 2 svc. Calls = Deaded......In less than a day:grin2:

Just sayin............Fieldpiece has sold them by the hundreds, Digi-Cool has sold them by the tens.
There are a lot of these in the field with no problems being experienced. I am

I have done several NU22b retrofits, all with no problem. The first I did was on

That is the best way to calibrate. They are then calibrated to the range you
will be using them in. Otherwise they will be calibrated to read an accurate 0psig.

Any 150 viscosity Mineral Refrigeration Oil should work fine.

If the SPK1 had a pipe clamp on it also, would be great for getting Approach,

Just not the current clamp design,...

There have been at least 2 mods to the internals since first release. All the ones
we had at the RSES meeting here were first generation blister pack.

There are three different internals out...

Looks like it will only be the first generation units that will experience intermittent
flow issues, and then only when introduced to an oil rich system. The latest internal
design on the manifold...

Nope, it just needs to be tweaked a little bit and it will be a DC killer. How long
have you had your SMAN3 ?

Primarily, it will prove to be too restrictive, which is one of the problems in the field
when the manifold fails to flow refrigerant. Port design and stems needs to be looked
at a little harder,...

I love Fieldpiece, have nearly everything available, and I love the Electronics on
the Sman3, but there are problems with that manifold which need to be addressed.

A redesign is in order.

I like the Cooper

Clamp on liquid line, read actual line temp, toggle and get ambient = Approach. :.02:

Probably due to the fact that you are applying bottle pressure to the manifold while
you are trimming, instead of system pressure?

Did you not see post #2, 2 hours after you posted the question?

The SMAN3 has been coming in real regular out here in West Texas. Been 13 of
them sold in the last 4 to 6 weeks, and some on the shelves. No problems reported
as yet, so that is a good...

I was pretty sure that was what you were referencing, like the ones used on flow
switches to protect against flutters in closed loop systems.

Real shame they don't make quality tools anymore. The service wrench below is

Fieldpiece Deluxe Silicone Test Lead Kit - ADK7

Enough said here. This is a Fieldpiece thread. PM me if you want to discuss it.

You would be wrong about the wholesale cost, and I know of at least one Supply

Probably the best way for you to resolve that issue, is to call JB....:D

How many perfectly round tight fitting joints do you get to see on a daily basis?

Roll off a little 7/8, slide a coupling on and see if it meets the criteria for the glue.

Even if it did, don't...

Just a tip......When you are ready to bag the SMAN up, turn it upside down to hold
the hook out. Slips right into the slot..........

JB and Robinair both make good pumps. I prefer JB, but I get service from them

I would ask the Vendor which brand gives better support if...

I guess I miss-understood the intent of your statement then. Seemed to be made
in a different line of thought.

Not real sure on that, just saw the reference a few replies up saying J/B "JustBetter"

My reply was simply made in response...

Somebody else needs to check the Patent Office. JB put a patent on the 4 ball
manifold in 1996.:oops:

I own nearly every Fieldpiece Acc head, and a stick meter. Have had them for years

Several years back, Hart Cooley did a monthley Tech Letter. I sure miss it.
