1592038700 Gas Leak Detector GB 16.09.2016
GDS41-GDS66-GDI41-GDI66
14/16
The GDS or GDI is calibrated at the factory. After installation, a zero adjustment maybe
required due to differences in environmental conditions.
If the GDS or GDI is exposed to a large leak it should be tested to ensure correct functionality
by electrically resetting the zero setting and carrying out a bump test. See specific Dixell
manual for this procedure.
Dixell recommends annual checks and gas calibration. Dixell also recommends sensor
replacement every 3 years or as required.
Calibration frequency may be extended based on application, but should never exceed 2
years.
In applications where life safety is critical, calibration should be done quarterly (every 3
months) or on a more frequent basis.
Dixell is not responsible for setting safety practices and policies. Safe work procedures
including calibration policies are best determined by company policy, industry standards, and
local codes.
Failure to test or calibrate the unit in accordance with applicable instructions and with industry
guidelines may result in serious injury or death.
The manufacturer is not liable for any loss, injury, or damage arising from improper testing,
incorrect calibration, or inappropriate use of the unit.
The testing and/or calibration of the unit must be carried out by a suitably qualified technician, and
must be done:
in accordance with this manual
in compliance with locally applicable guidelines and regulations.
NOTE:
The full procedure for the specific calibration and the technical equipment to use is
described on Dixell Calibration Manual.
