Periodic Inspections and Calibration

Although the wireless transmitter is maintenance free, regular
inspections may still be necessary. The inspection frequency depends
on operating conditions, including operating under extreme
temperatures, exposure to contaminants or gas concentrations greater
than the lower explosive limits. A calibration inspection must be
included as part of a routine maintenance to ensure proper operation of
the gas detection unit.
