I picked up the 14571 today.
Put them on a refrigerant tank with a cps vg2000 and the inficon piolet.
During the pull down they were all a little off. one I got down 400 microns they were all within 50 or so microns. I dont get these things lol. I didnt think the cps worked properly. when I would shut a valve and see if the vacuum holds the cps would drop a lot on some systems ( like 300 microns). So I was not so sure about it. Thats when I picked up the thermal.
When this thing is in a vacuum do you guys check the calibration and adjust of needed or do you calibrate in the beginning and leave it alone. While i was pulling down the tank the thermal was 200 microns above the inficon. so my buddy checked the calibration and it was off ( I set it wrong ) he adjusted it in the vacuum and it was right with the inficon. once the unit was put back to atmosphere I checked the calibration and it was ok.
Also how do you guys store this analog instrument in you vans to keep them lasting. Im not sure if im having second thoughts....
