If you unintentionally switch the gas compensation to the incorrect setting, the accuracy of the
measured flow and volume values may be significantly reduced. The tables below show examples of
incorrect gas compensation settings and the resulting inaccuracies:
Incorrect Balance Gas Setting (N

)
Incorrect Agent Percentage Setting
