11. 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 exception
is noted on the individual calibration certificate.
Mensor reserves the right to change specifications without notice.

, absolute <=> gauge.
Measuring range
552 ... 1,172 mbar abs. (8 ... 17 psi abs.)
Accuracy
1)
0.01 % of reading
Pressure units

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
3) 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.
4) Ranges from 1500 to 2000 psig will be sealed gauge transducers.
5) 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.
