9. 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 Asso-
ciation 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.

0.020% of reading
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) The negative portion of a bidirectional range has the same accuracy as the equivalent positive range.
