10- To reset the zero, wait until the reading has stabilized and select Zero Offset in the
Ctrl (Control) menu. Note that the Zero Offset process can take about 20s for a photodiode.
It is much quicker for other detectors. You are now ready to make an accurate measurement.
Notes:
• Refer to specific power detector documentation for complete installation and operating
instructions.
• The power detectors are thermal sensors sensitive to temperature variations.
For high-precision measurements, it is recommended to:
• Allow the power detector temperature to stabilize before zeroing the P-LINK.
• Do not touch the detector head when handling the power detector. Touch only the stand.
• Avoid forced airflow or drafts around the detector.
11- Apply the laser beam to the detector head.
12- The laser beam average power will be displayed in three ways for your convenience:
a. Digitally for real time measure.
b. On a histogram to allow the laser beam’s long-term stability to be evaluated.
c. On a digital needle for laser tuning.
