Candela Corporation AlexTriVantage Laser System
Calibration Schedule
The measurement circuits should be calibrated annually to insure accurate delivery of
treatment energy. Measurement circuit calibration should be performed by a qualified
Candela Service person as part of a "preventive maintenance" visit. During the visit, other
subsystems of the laser system will be inspected, adjusted (if necessary) and/or repaired as
required. Contact Candela Customer Service for details on "preventive maintenance" or a
service contract (if available).
Introduction
In normal operation, the Calibration procedure is provided for the user to calibrate the energy
output of the laser system. During that procedure, the handpiece is inserted in the calibration
port, the laser is pulsed, and the energy output of the handpiece is read by internal laser
energy detectors. The system determines the power and energy levels necessary to provide
the correct delivered energy for the currently selected fluence setting.
The internal laser energy measurement circuits themselves must be calibrated at least once
a year by a qualified service technician. The internal energy calibration procedure (or "Laser
Energy Circuit CAL") is described in this section. The procedure requires an external laser
energy meter whose calibration is traceable to the appropriate national standards agency.
The external laser energy meter used must be appropriate for the specified output of the
laser system, with an accuracy of ± 6% or better, and a resolution of 1mJ. This procedure is
part of the normal preventive maintenance service procedure.
Parts List
1. Energy meter (OPHIR with 10A-P head).
2. Delivery System with known good transmission (85%).
3. 3mm Handpiece with clean optics.
Note: The procedures contained in this section are service procedures to be performed
by appropriately trained technicians. They are not to be performed by the user.
Warning: The electrical and laser radiation hazards present during servicing
of the AlexTriVantage can be extremely dangerous if proper safety
precautions are not taken. The AlexTriVantage is to be serviced only by
qualified technicians who have received appropriate training from Candela.
Any attempt by an unauthorized person to perform any service procedure will
void any warranty on the laser system.
