4 Specications
Accuracy specications presented herein are obtained by comparison with primary standards traceable to
the National Institute of Standards and Technology NIST). A calibration data report has been provided with
your new CPC8000 instrument, traceable to NIST. The calibration program at Mensor is accredited to both
ISO/IEC 17025:2005 and Z540-1-1994 by A2LA. Mensor, LP is registered to ISO 9001:2008.

, absolute <=> gauge. With
gauge pressure transducers, the measuring range of the transducers must begin with -1 bar (-15
psi) in order to carry out a complete absolute pressure emulation

(1) It is dened by the total measurement uncertainty, with the coverage factor (k = 2) and includes the intrinsic performance of the instrument, the measurement uncertainty of the reference instru-
ment, long-term stability, inuence of ambient conditions, drift and temperature eects over the compensated range with recommended zero point adjustment every 30 days
.
(2) 0.01 % IS-50 accuracy: Between 0 ... 50 % of the full scale, the accuracy is 0.01% of half of the full scale value and between 50 ... 100 % of the full scale, the accuracy is 0.01 % of reading
.
(3) FS = full span
.
(4) 0.008 % IS-33 accuracy: Between 0 ... 33 % of the full scale, the accuracy is 0.008% of one third of the full scale value and between 33 ... 100 % of the full scale, the accuracy is 0.008 % of reading
.
(5) 0.008 % IS-50 accuracy: Between 0 ... 50 % of the full scale, the accuracy is 0.008% of half of the full scale value and between 50 ... 100 % of the full scale, the accuracy is 0.008 % of reading
.
(6) The minimum calibrated range of absolute transducer(s) is 600 mTorr.
(7) Ranges from 1500 to 2000 psig will be sealed gauge transducers.

It is dened as the combined eects of linearity, repetability and hysteresis throughout the stated compensated temperature range.
(9) 365 days for 0.01% IS-50, 0.008% IS-33 and 0.008% FS accuracy. For 0.01% FS accuracy, 180 days for pressure ranges below 1 bar (15 psi) gauge or absolute, and -1 ...1 bar (-15 ... 14.5 psi)
bidirectional. 365 days for the remainder of the specied ranges
(10) For a pressure type emulation, we recommend a native absolute pressure transducer, since the zero point drift can be eliminated through a zero point adjustment.
