Series 979 ATV Transducer
If using a gas other than air/nitrogen in the system, then the user will need to
change the gas correction factor for the Hot Cathode to provide an accurate
pressure reading (see
Gas Correction – GC
in the
Set Up Commands
section). The table below shows GC values for some commonly used gasses.
These correction factors are all relative to the nitrogen factor (which in the
case of the Hot Cathode is 1). For example, if using Argon gas in the system,
use the GC command as follows: @253GC!1.29;FF.
