When selected, ALARM TEST MODE menu button will simulate alarm conditions by incrementing the gas
readings from 0 for all active gas channels at 5% full scale. Once the concentration has reached full scale, the
concentration will begin to decrement back to 0 and the controller will exit the test mode. The test mode can
also be terminated at any time during the test cycle by selecting the ALARM TEST MODE menu button
again.
