    USER MANUAL Maintenance Gas monitors are safety instruments. Recognizing this fact, TELEDYNE OLDHAM SIMTRONICS recommends that a functional test be performed on every portable gas monitor prior to each use. A functional test involves injecting a gas of sufficient concentration at the sensor level to trigger pre-set alarms.
