6.7.3 SETUP additional menu items: Reference sensor

Sensor number of the currently connected CPT6000 reference pressure sensor
1
Start of measuring range and end of measuring range for the currently connected
2
CPT6000 reference pressure sensor
Basic pressure unit of the CPT6000 reference pressure sensor
3
Accuracy of the measuring chain of the CPH7650 with connected CPT6000
4
reference pressure sensor
Pressure type of the currently connected CPT6000 reference pressure sensor
5
(overpressure (gauge pressure) or absolute pressure)
Duration for which the CPT6000 reference pressure sensor was unacceptably
6
overloaded.
If the value here is not equal to zero, then it is highly probable that the
instrument no longer meets its specified class accuracy. The only solution
for this is an immediate recalibration. (For absolute pressure sensors
< 1 bar abs. (< 15 psi abs.), this function is deactivated, since for these
measuring ranges atmospheric pressure already represents an overload)
Current measured value of the connected CPT6000 reference pressure sensor
7
This menu item only appears if the CPH7650's reference pressure sensor is an
8
absolute pressure sensor.
Through this menu option the measured value of the reference pressure sensor can
be adjusted. This should only be used, however, as close as possible to the absolute
zero, and using a reference that is at least 4 times more accurate.
