Operating Instructions - CPC6050
Modular Pressure Controller
CPC6050
10 Calibration
The CPC6050 automatically adjusts the pressure reading for the effects of temperature and non-linearity
within the calibrated temperature range of 15-45°C. The process is referred to as dynamic compensation
because each reading is so adjusted before it is output to the display or to a communication bus. Thus, a
calibrated CPC6050 operated within its temperature band, and with proper zero and span adjustments,
will provide accurate pressure measurements.
The CPC6050 should have the calibration verified periodically to ensure stability. The recommended
calibration interval for this instrument is given in the Specifications section under "Calibration Interval" in
Section 4.1.

10.2 Environment
For maximum accuracy, allow the CPC6050 to warm up a minimum of 15 minutes in ambient temperature
within the compensated range prior to a calibration. In addition, the instrument should be at rest on a
stable platform that is free of excessive vibration and shock.
10.3 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 to
the Expression of Uncertainty in Measurement (GUM) are applied, the instrument meets its accuracy
statements as required by ISO/IEC 17025:2005, or other applicable standards.
10.4 Media
The recommended calibration medium is dry nitrogen or clean dry instrument air. A height variation be-
tween the standard and the CPC6050 can cause errors. A calculation should be made to compensate for
this difference. This compensation can be done in Section 10.10 - Head Pressure.
