CAUTION! Use of controls or adjustments or performance of
procedures other than those specified herein may result in
hazardous radiation exposure.
The emitter power level can be re-calibrated, and the current
checked as described below. You will need a power meter with
appropriate calibrated wavelengths, single mode test leads, an anti-
tamper label, and a 2.54 mm (0.1”) programming jumper.
Check the calibration certificates on your reference equipment to
ensure current validity.
•
Put the instrument in calibration mode.
•
Connect a calibrated power meter with a known good patch
lead (the patch lead loss forms part of the calibration
condition).
•
Press [Source], leave in, and then press [ ] and [Level].
The display will now show the expected power level, cal
factor (main display) and laser current in mA (top right). Note
the existing values for future reference. Set meter wavelength
to match.
•
Adjust the [-/+] button to change the source output level, to
match the displayed level on the source display, or to re-enter
a known cal factor (The laser current can not go above a level
that has been set for the individual laser during manufacture).
•
Note new calibration values and laser currents for future
reference, then press [Set] to store settings and exit, or [Exit]
to exit without storing settings.
•
Remove the programming shunt, and place a new sticker
over the aperture.
