5. Turn off the gas regulator valve and allow clean air to circulate over the sensor and the gas
to dissipate. After removing the gas the sensor should recover and return to
Operation.
It may be necessary to ventilate the room with fresh air for the sensor to recover. The time
for the detector to recover will depend upon the concentration of gas detected by the
sensor and the time period but is typically less than 5 minutes. It is recommended that the
sensor is not subjected to test gas for a prolonged period (>3 minutes) as recovery may
become significantly longer.
Please ensure the regulator is switched off after use and the bottle is stored in a ventilated
!
space.
See section 3.1 for supplementary information of Gv voltages at different operational states.
The detectors relays are normally energized, so the operation can also be tested by isolating
power to the detector.
