Gas Cal: INFICON's gas compensating sensors provide a measurement of the
emission caused by background gases. The gas calibration factor is used to null
this portion of the signal from the main flux sensor measurements. If the EIES rate
reading with no evaporation is negative, decrease the Gas Cal. parameter until the
rate averages near zero. If the rate reading is positive with no evaporation,
increase the Gas Cal. parameter until the reading averages near zero.
Enable Gas Sensors: Click to select the gas compensating feature. Requires gas
compensating (GC) sensors.
