2.4.3 Detector Calibration
The internal electronics of each EIES detector module are pre-calibrated at the
factory. To compensate for background noise once installed to a system, the
following calibration must be performed.
NOTE: Allow 1 hr warm-up for the PMT to reach optimum stability. If you replace
or exchange a detector, you must recalibrate!
To calibrate a detector, select the Channel tab of the System Edit dialog box.
Select the Channel you want to calibrate. Sensor emission should be off.
Figure 2-18 System Edit Channel Tab
Verify that a “No Response!” error message is not shown below the Start button in
the calibration frame. If it is, check the detector to controller cable. You can also try
powering the controller off, then on. Establishing ethernet connection may take a
minute or more.
Set the detector Update rate to 10 Hz and Cal Readings to 10.
When there are no errors, click the Start calibrate button. The screen will indicate
the calibration process and end with a Calibration Complete message.
Select and calibrate any additional detector channels.
