4 LIO Power Verifi cation
4.1 Setup the system in a similar confi guration as shown in Figure 4-2, to direct the
LIO distal output beam into the wattmeter cell.
4.2 Set the exposure time to CW.
4.3 Set the treatment power to 0.10 W then press the Standby/Ready key.
4.4 Fire the laser and record the power reading as determined from the Wattmeter.
4.5 Repeat steps 4.3 and 4.4 for each value listed in the LIO section of Table 4-1.
5 Energy Matrix Completion
5.1 Complete the matrix by multiplying actual power by actual exposure time and
recording the result, as shown in the example below.
x
5.2 Ensure that all calculated results are within the values listed in each matrix cell.
The listed values are ±15% of the set energy.
• If all calculated energy values are within the specifi ed limits, the system
calibration is OK.
• If any of the calculated energy results are not within the specifi ed limits,
the Terminal Effi ciencies will need to be adjusted. Perform the Setting the
Terminal Effi ciencies procedure following Table 4-1 or
call Alcon Technical
