| Measure Power: |
| 1.) |
Move the Power/Wavelength switch to W.
|
| 2. |
If expected power is >10 mW, slide the power step attenuator over the sensor by moving the attenuator control toward the sensor.
The Filter Position indicator will be black when the attenuator is in place and yellow when the attenuator is not in place. DO NOT EXCEED 0.5 W/cm2 without the attenuator in place. DO NOT EXCEED
30 W/cm2 with the attenuator in place.
|
| 3.) |
Press and hold down the power Sample/Hold button. |
| 4.) |
Insert and center the sensor in the laser beam for a minimum of 2 seconds. Note: Keep the sensor close to normal incidence with respect to the beam to maximize accuracy and minimize hazardous back reflections. If the LaserCheck emits an audible beep tone and the display shows three dashed lines (---), the power level is over
maximum power. |
| 5.) |
Release the Sample/Hold button and remove LaserCheck from the beam. |
| 6.) |
The peak power measured during the time the Sample/Hold button was held down will be displayed. After 10 seconds, LaserCheck will automatically shut off. |
|
|
| Set Wavelength: |
| 1.) |
Move the Power/Wavelength switch to λ. The current wavelength
will show on the display. |
| 2.) |
Set the wavelength from 400 to 1064 nm with the Wavelength
Increment or Decrement buttons. (Beyond 999 nm the display will
read 000 to 064 for wavelengths from 1000 to 1064 nm.)
NOTE: The wavelength setting is stored. Changing the wavelength
setting is not required unless the wavelength being measured is
changed. |
|
|
| Warranty |
| LaserCheck is warranted against all manufacturing defects for one year from date of purchase. Contact Coherent for complete warranty statement. |
|
|
| Laser Damage Warning |
| LaserCheck sensor will be damaged if the specified maximum power density is exceeded. Warranty is void if maximum power density is exceeded. |
|
Move the Power/Wavelength switch to W.

2.)

If expected power is >10 mW, slide the power step attenuator over the sensor by moving the attenuator control toward the sensor.
