Power measurements
Output measurements
Measure output power at the focusing optic (output aperture) of the marking head. When comparing
output power to input power measurements, make sure you set the same PWM power percentage as used
in the Input measurements section above. Typical power loss through an FH Series marking head (measured
output power versus measured input power) is approximately 7%.
To begin output power measurements, perform the following steps:
Danger
serious
personal
injury
This product emits invisible infrared laser radiation at the 10.6 µm
CO
2
wavelength. Since direct or diffuse laser radiation can inflict
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.
1 Ensure that all personnel in the area are wearing the appropriate protective eyewear.
2 Open Digital Scope and 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 center of the focusing optic’s beam path.
Hold the Power Wizard approximately one-half the distance from the bottom of the lens mount to
the focal plane of the lens to ensure that the Power Wizard is in the path of a defocused beam.
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 Toggle Lase to turn off the laser.
9 Repeat Steps 3 through 8 two or three times to get a good average output power reading.
If power loss through the marking head exceeds approximately 7%, remove the focusing lens and take an-
other set of output power measurements. Excessive power loss through the focusing lens may indicate that
the lens is dirty. Inspect the lens for contaminants and, if required, carefully clean the lens as described in
Maintenance in the Maintenance/Troubleshooting chapter.
If the FH Flyer marking head is mounted in a non-standard configuration (without using the SYNRAD
designed L-bracket and Mounting Rail), verify that alignment to the laser is correct. Ensure that the beam is
located in the center of both input and output optics.
