5 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. This test does not, in any event, replace a full calibration of the sensors.
If a gas monitor does not respond correctly to a gas test, a full calibration with a calibration gas
is mandatory.
These recommendations are consistent with applicable industry safety protocols and with the
standards and directives relative to the safety of industrial sites. TELEDYNE OLDHAM
SIMTRONICS is also not responsible for procedures performed onsite.
The gas monitor is factory-programmed to display a maintenance alert if a calibration
has not been performed in the last twelve months (the message
Calibration due will
appear on the screen).
The operations explained in this chapter must be performed by authorized, qualified
personnel only, as they could adversely affect detection safety.
