i. Block off laser radiation to the detector. To reset the zero, wait until the reading
has stabilized and click on the Set Zero in the Main Control Ribbon parameters
menu.
ii. If you have connected a photodiode, you must cover the diode and the zero has to
be done for all scales. You will not have to do this manually for each scale as this
is automatically done when you turn “on” the zero. In some software versions, a
message appears requesting you to put the black cover over your photodiode.
Touch the OK button after you have done so. The PC-Gentec-EO passes through
all the scales to determine the zero diode for each scale.
Notes:
• Refer to specific power detector documentation for complete installation and operating
instructions.
• Power detectors are thermal sensors and are thus sensitive to temperature variations.
For high-precision measurements, it is recommended to:
• Allow the power detector temperature to stabilize before zeroing the PC-Gentec-EO.
• Touch only the stand when handling the power detector. Do not touch the detector head.
• Do not zero adjust the energy detectors, such as the QE series.

Avoid forced airflow or drafts around the detector.
