Sensor Parameters

Gas Correction Factor C1
The output signal of the VSP/VCP depends on type and composition of the gas
being measured. The unit is adjusted for N
pressure display can be corrected below 0.1 mbar by setting correction factors
for the Pirani sensor via RS485.
The measurement result of the Pirani sensor is then individually multiplied with
the corresponding correction factor by the units microcontroller. The VSP can
thereby provide a corrected pressure signal output.
