Specifications
Accuracy specifications presented herein are obtained by comparison with primary standards traceable
to a national metrology institute or recognized international standard organization. These specifications
are obtained in accordance with the ISO Guide to the Expression of Uncertainty in Measurement (GUM).
The calibration program at Mensor is accredited by the American Association of Laboratory Accreditation
(A2LA) as complying with both the ISO/IEC 17025:2005 and the ANSI/NCSL Z540-1-1994 standards. If
there is an exception to the requirements and recommendations of Z540 during a calibration the excep-
tion is noted on the individual calibration certificate.
Mensor reserves the right to change specifications without notice.

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

1)
It is defined 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
instrument, long-term stability, influence of ambient conditions, drift and temperature effects over the compensated range with recommended zero point adjustment every 30 days.
2) FS = full span
4) Ranges from 1,500 to 3,045 psig will be sealed gauge tranducers
5) The minimum calibrated range of absolute transducer(s) is 600mTorr
6)
It is defined as the combined effects of linearity, repeatability and hysteresis throughout the stated compensated temperature range
7) For a pressure type emulation, we recommend a native absolute pressure transducer, where the zero point drift can be eliminated through a zero point adjustment.
