Full specification obtained after 30 min. warmup time
The GD10P is factory calibrated and does not require any adjustments before operation. A check
prior to putting into service should however consist of:
1) Clean the optical surfaces.
The detector may have been collecting dirt after being initially installed. It is thus crucial to
clean the optical parts before testing the detector (refer to Paragraph 7.1 “Cleaning of
optical lens/mirror”).
2) Do a gas test.
To make sure the detector works fine you should as a minimum do a function check as
described in paragraph 7.2 “Function test”.
Optionally you may do a full calibration test as described in paragraph 7.3 “Calibration
test”.
Startup period can be up to 10 minutes under very specific conditions. This
corresponds to the temperature adjustment time of the different components.
If the analog output of the detector stays at 0.6mA after 10 minutes then the detector
could have a zero drift issue. This issue can be solved by applying a “Re-Zero” to
the detector. This procedure is described in section 7.4.
