4- Switch the S-Link ON (plug it in).
5- Power heads will default the S-Link to power measurement; energy heads will default the S-
Link to energy measurement.
6-
Remove the head’s protective cover.
Put the detector head into the laser beam path. The entire laser beam must be within the
sensor aperture. Do not exceed maximum specified densities, energies or powers. For the
most accurate measurement, spread the beam across 60% to 80% of the sensor area.
Attention: Power heads can be used with both CW and pulsed lasers.
- Energy heads can only be used with pulsed lasers.
7-
For power heads (using the S-Link), go to step 8. For energy heads, go to step 11.
Adjusting the zero (steps 8 to 10)
8-
Block off laser radiation to the detector.
9-
The power read by the PC S-Link when no laser beam is incident on the detector may not be
exactly zero. The detector is either not thermally stabilized OR there was a heat source in the
field of view of the detector when you turned on the S-Link.
10- To reset the zero, wait until the reading has stabilized, right click and select Zero Offset. 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, we recommend:
•
Allowing the power detector temperature to stabilize before zeroing the S-Link.
•
Not touching the detector head when handling the power detector. Touch the stand.
•
Avoiding forced airflow or drafts around the detector.
11- Apply the laser beam to the detector head. The laser beam average power or energy will be
displayed on the computer screen.
12- If the USB drivers and/or PC S-Link have not been installed, install the USB drivers (see 3.1.1)
then install PC S-Link (self-directed).
13- Start the PC S-Link software on the PC. Click Start / Programs /GENTEC-EO/ PC S-Link.
14- To connect the PC S-Link to the device, select the correct COM Port (see section 3.2.1) and
click Reconnect. You should see values pertaining to the current settings on the PC S-Link.
15- To replace a head, turn off the PC S-Link, unplug the S-Link, insert the new head, plug in the S-
Link, and restart the PC S-Link.
