Testo 510 users

[gasguy]

Just recieved my new testo 510 manometer. Woo hoo! New toys! I was suprised with the size/weight of the unit. It looked bigger in the pics.
Is there a maximum length allowed for the tubing used? Can't find any mention in the destructions. Any tips/tricks with using this baby? Is the accuracy good for measuring duct static pressures? Can't wait to try her out!

Turn it ON before connecting to system. It zeros on startup.

Don't turn it upside down while measuring. It will change your reading.

Yes, I love my 510. Great tool!

If we stocked them, I'd sell one every time I used it on a service call with a tech.

If you don't already have them, get some 1/4" barbed tees and some extra lengths of tubing so you can T into the furnace pressure switches.

That's already on the list. Also wated it for pd through carrier 90% furnaces. Part of their new inspection routine for hx failures. The more I think about it the more handy this thing will be!

There is no max length on the tubing, however, a longer tube will give you a more stable reading due to the dampening of the signal. The 510 also works very well with a pitot tube for measuring airflow and has adjustable air density for accurate measurement and a timed traverse mode.

The cover can also be installed on the bottom of the meter when you are using it.

The 510 incorporates a temperature compensated sensor so the meter will remain very stable. For highly accurate readings, the 510 should be kept in the same position for the measurement that it is zeroed in. Most of the time I just attach it to the duct via the magnet on the back of the instrument the zero the sensor. The long term stability is excellent.

As a student new to the industry I've been trying to figure out which tools I'm going to need. I was looking at the 510 but was wondering If I can use it to check gas pressures (natural/LP). It is described as a differential manometer.

Where do you get the 1/4" barb tees?went to Ace,homedepot,lowe's,supply house none of them have it,well homedopot got the 3/8" but not 1/4". i been looking for this for awhile.

Aquarium store..

Yes. It will work great for you!

Most 90% gas valves are enclosed combustion. The gas valve references burner box pressure instead of atmospheric. So, you need to have differential ability when checking outlet gas pressure.

Aquarium store..

or Trane Parts. The Louisville store used to have them on the shelf. It's been a few years, but that's where I bought mine.

Also, any supply house that services the pneumatic controls industry.

A quick question. On a 90% furnace with a enclosed burner box. You must use a differential manometer to adjust outlet pressure? If so, do you just T in somewhere between the burner box and pressure switch?

Thanks

[ch4man]

you can use a single port manometer if you take the burner cover off...

or just pull the hose off the gas valve. remember your manometer must reference the same pressure zone as the air side of the gas valves internal regulator
