Gas Detector Processing Operation under Outrange Status
Users should avoid to have sensor impacted by the gas with a pressure value
greater than the maximum of the detector, which might affect the service life and
precision of the detector, or even directly damage detector.
When user accidentally makes outrange operation, he should evacuate the
instrument out of the detecting site and place it in the clean air for more than half
of an hour. During this time, user should observe whether the density value of the
instrument is keeping decreasing or not. If it can straightly go down to normal
value, then it can continue to use after the zero calibration of instrument. If the
instrument has evacuated from hazardous area after the outrange operation and
user has placed it in clean air for hours, the density value still remains high, then
it should be sent back to the manufacturer or agent for maintenance, be ready to
replace the sensor.
Special Note: detector damage resulted from outrange operation is not within
the warranty.
③
Detector Calibration and Warranty
We guarantee all detectors were being precisely calibrated with certain
density standard gas. It’s not necessary for user to re-calibrate the detector after
purchase unless encounter special situation. Also the calibration need to be
operate under the guidance of the professional.
All GT903 series products we provide 12-Mounths warranty for the detector
and 3-Mounths warranty for the accessories. Beside , we have free calibration
