Power measurements
To begin input power measurements, perform the following steps:
1 Ensure that all personnel in the area are wearing the appropriate protective eyewear.
2 In Digital Scope, use the slider to set the desired PWM power percentage, which appears in the Laser
Duty Cycle box.
3 Ensure that all personnel are clear of the beam path and then press the Toggle Lase button.
4 Push and hold the Power Wizard’s Reset button for 2–3 seconds.
5 Release the Reset button and quickly verify that the display reads 0.0 W (±0.3 W).
6 Immediately place the Power Wizard’s target area in the beam path centered on, and close to, Flyer’s
Expander Telescope (input aperture). See Figure B-1. Do not allow the Power Wizard to contact the
Expander Telescope as this may damage the expander’s optical elements.
Danger
serious
personal
injury
This product emits invisible infrared laser radiation at the 10.6 µm
CO
2
wavelength. Since direct or diuse laser radiation can inict
severe corneal injuries, always wear eye protection when in the same
area as an exposed laser beam. Do not allow the laser beam to contact
a person. This product emits an invisible laser beam that is capable of
seriously burning human tissue.
Always be aware of the beam’s path and always use a beam block
while testing.

7 Keep the unfocused beam centered on the Power Wizard’s target area until you hear a series of beeps.
This indicates the measurement cycle has ended. An automatic hold feature maintains the current
reading for approximately 20 seconds or until the Reset button is pressed.
8 Press Digital Scope’s Toggle Lase button to turn o the laser.
9 Repeat Steps 3 through 8 two or three times to get a good average power reading. When measuring
power levels above 100 watts, give the Power Wizard time to cool between measurements.
