PACE 5000 Pressure controllers /calibrator

[GA_PMEL_RF]

Any one have any history on a PACE 5000 Calibrator with the CM3-30 PSI Module (High Precision).  They have some real tight specifications and was wondering if they are reliable and holding those specifications.    Fluke has degraded the 72XX xi Series specifications stating Ruska had over stated the actual tolerances they will hold.

Exelon Lab said they saw one several years back but have not seen it back.  May not be a very good standard even though it's a modular type pressure standard.

We still support a CM1-B-13G module of the PACE 5000 system for one of our clients since 2013. It is not the most accurate option but it seems pretty reliable. It was adjusted a few times and the valves had to be repaired a couple years back.

Ok .  Thanks for the feed back.   Since Fluke down graded the Ruska 7250Xi an 7252i series specifications we had to look for ways to get 4:1 for real low pressure calibrations without using dead weight 2465A. 
7250xi 20% to 100% 90 day +/-0.006%  ; 1 year 0.009%
i-Class  +/- 0.005% of rdg from 40% to 100%
+/- 0.005% of 40% FS from 0- 40%     90 Day =/- 0.005% ;1 year +/- 0.009%
Neg Pressure (opt) Greater of +/- 0.005% of 40% FS or +/- 0.00075 psi(0.005 kPa)  Posted by fluke 26 May 2021.
