2.1 WITH GENTEC-EO MONITORS
To operate the PH and PE Series photo detector, connect the detector head to the input socket on
Gentec-eo monitors with the cable supplied by Gentec-EO before turning the monitor on. (See
monitor
’s instruction manual.)
Adjust the reading to zero before measurements for best accuracy. See procedure in section 2.2
below.
If you are using the fiber optic adapter, put the black protective cover on the detector head before
making the offset nulling.
If you want to subtract the room light do the offset nulling with the cover off.
2.2 QUICK POWER MEASUREMENT PROCEDURE
This section will show you the fastest way of making a laser power measurement with Gentec-eo monitors
and power detector.
The monitor automatically recognizes all Gentec-EO photo detectors heads of version 5 or higher. Then
the monitor automatically downloades all custom technical data for the detector from the EEPROM in the
DB-15 connector. This data includes sensitivity, model, serial number, version, wavelength correction
factors, and time response.
