Detector Gain

4-4 48iQ Instruction Manual
The Detector Gain is determined at the factory and should only be
adjusted by a qualified technician. The only time the Detector Gain should
be adjusted is if there were changes to the elements that affect the light path
or detection. Zero Air should be sampled when calibrating the Detector
Gain. There are two ways of calibrating the Detector Gain: From the
Home Screen>Settings>Advanced Measurement Settings>Optical Bench
Settings>Continue To Detector Gain Calibration. The user can manually
change the detector gain by clicking on the first cell below the Detector
Gain description. The user will be brought to a keypad screen where a new
value can be entered.
However, it is suggested to run an Auto Calibration for the Detector Gain.
This is done by pressing on the cell labeled Start located in the Detector
Gain column. Allow up to 5 minutes for the Detector Gain to be
calibrated. The user can Stop the calibration at any time by pressing the
Stop button located in the Detector Gain column.
The user can set the Detector Gain to factory defaults by pressing on the
cell labeled Default Gain located in the Detector Gain column.
