I have four sets of gauges and the way I check my gauges is I got a Trojan tee coupler that I can attach two or three set at once and if they all read the same I know the gauges are pretty accurate. If they are not then I either calibrate them or trash them but one thing I do every year is buy a new set of 72 in hoses.

This is a fascinating discussion so far.

I still have one set of gages and they are accurate enough. I been thinking about purchasing another. What about the CPS brand gage? I like it. Does anyone recommended or not recommend it?
Thanks.

I would not want to keep you waiting Dice.
Besides normal manifold sets, a market man should at least have one dual high gauge set. It sure helps when checking your defrost differential.
As Dave has already mentioned a dual low and a dual high are a good idea.
I keep a hose with a depressor on my low side only. My common and high have none.
But my high side does have a CA1 manual depressing valve. This helps on smaller systems. I just back off the depressor and pump all the liquid into the suction side.
Plus I just don't like frozen fingers.
A Diamond is just a piece of coal, that made good under pressure!

I'm gonna spring for the digital set soon.
I'll order them thru WalMart so if I dont like em, I can take em back and get my money back. 
(24 sets of gages .... sheesh!)

Calibrate Gauges
The best way to calibrate gauges is to hook to a drum of r-22 (or whatever you have handy) that has been stored in a controlled ambient temperature for several hours. then calibrate gaug to pressure -temperature chart. this will never lie as long as you use virgin refrigerant.

OH .... and I guess you got a special one just for measuring oil pressure at the pump scraeder?!?!?!
