Energy Detectors Calibration
Lumenis Pulse 120H UM-10012510 Rev. F
Page 123
The Lumenis Pulse 120H system incorporates internal energy detectors
which are used to control lasing energy. The energy detectors check
compares the internal energy reading to the reading from an external
power meter.
WARNING:
All personnel in the immediate area must wear eye protection rated spe-
cifically for the Holmium laser.
NOTE:
Optical components must be clean before the energy detectors check is
performed.
1.
Verify that all personnel are wearing the appropriate laser safety
eyewear.
2.
Position a calibrated, external power meter 15 cm (6 inches) from the
output end of the optical fiber.
3.
Turn on the laser as instructed in the
Normal Operation
chapter of this
manual.
4.
Set the laser system to deliver
5
Watts of laser energy.
5.
Target the aiming beam at the detector disc of the external power
meter.
6.
Set the laser system to
READY
mode.
7.
Press the footswitch to deliver the laser energy into the detector disc of
the external power meter. Maintain delivery of the laser energy for 20
seconds.
8.
Release the footswitch and record the external power meter's reading.
9.
If the external power meter reading falls above or below 20% of the
requested energy on your laser, discontinue this procedure and contact
your local Lumenis service representative.
