Mensor/WIKA Operating Instructions Series CPG 2500
Digital Pressure Gauge
SERIES CPG 2500
In absolute emulation mode the atmospheric pressure reading from the barometric
reference transducer is added to the gauge pressure reading of the active channel to
emulate absolute pressure.
8.1.3 Calibration
The Barometric Reference Transducer can be calibrated in exactly the same manner as
the other installed sensors as described in Section 10, Calibration.
8.1.4 Specifications
Accuracy: 0.01% of reading. Uncertainties include all pressure effects, temperature ef-
fects over the calibrated range and calibration stability for six months after re-zeroing.
Pressure Range: The standard Barometric Reference Transducer is calibrated from 11
to 17 psia.
Resolution: 6 digits.
8.2 Barometer
The CPG 2500 can be ordered as a Barometer. It is a very stable, absolute pressure
sensor used to accurately measure local atmospheric pressure. The channel setup in-
formation as explained in this manual also applies to the Barometer. The only difference
will be the adjust tab setup for zero and sea level adjustment.
8.2.1 Zero and Sea Level Adjustment
Zero:
Zero can be adjusted on this tab and the main screen view (if selected) when the
padlock icon is unlocked. Press the Zero key to enter a zero pressure offset.
Sea Level:
Sea level correction can be adjusted on this tab and the main screen view (if
selected) when the padlock icon is unlocked. Press the sea level key to modify the sea
level correction settings.
The elevation offset pressure will always be positive unless the Barometer is below sea
level. The following table shows the calculated pressure values at various elevations.
