8.3.2 Environment
For maximum accuracy, allow the CPC8000-H to warm up a minimum of 15 minutes in ambient temperature within the
compensated temperature range prior to a calibration. In addition, the instrument should be at rest on a stable platform that is free
of excess vibration and shock.
8.3.3 Pressure Standards
Mensor recommends the use of appropriately accurate primary pressure standards when calibrating this instrument. Such
standards should be sufficient so that when the techniques of the ISO Guide of the Expression of Uncertainty in Measurement
(GUM) are applied, the instrument meets its accuracy statements as required by ISO/IEC 17025:2017, or other applicable
standards.
8.3.4 Media
The recommended calibration medium for the primary and secondary transducers is the same media that is on the label of the
CPC8000-HM hydraulic module. The recommended calibration medium for the optional barometric reference transducer is dry
nitrogen or clean dry air. A heigh variation between the standard and the CPC8000-H can cause errors. A calculation should
be made to compensate for this difference. This compensation can be done following the instructions from Section 9.10 Head
Pressure. It is recommended to use the calibrating device to calculate the height correction rather than the CPC8000-H when
calibrating the internal sensors.
