Why does the flow rate not read zero when no gas is flowing on my TSI Instruments CERTIFIER FA Test Equipment?

  If the flow rate on your TSI Instruments Test Equipment doesn't read zero when no gas is flowing, especially when set to N O, it might be because the meter wasn't purged with the gas displayed on the controller. To resolve this, purge the meter with the gas displayed on the controller or press the gas select key to change to the desired gas.
