Value
GAS I
GAS N2 I  Gas: nitrogen / air (factory setting)
GAS AR I  Gas: argon
GAS H2 I  Gas: hydrogen
GAS HE I  Gas: helium
GAS NE I  Gas: neon
GAS KR I  Gas: krypton
GAS XE I  Gas: xenon
GAS COR I  Calibration factor for other gases by
manually entering parameter COR
The calibration factor COR allows the measured value to be calibrated for other
gases (→ characteristic curve in  [1] … [16]). This parameter is effective in the
entire measurement range of the gauge.
Precondition: Parameter "GAS COR" is set (except capacitance gauges).
This parameter is not available with the measurement unit: Volt.
