2. Use the scroll bar to adjust the response factor in the Response Factor
area.
3. Apply constant power to the thermopile head until the graph stabilizes.
4. Click Scale.
5. Block the laser for several moments to allow the head to cool down.
6. Click Ready.
7. Unblock the thermopile head.
8. Take a second reading.
Adjusting Energy Calibration Factors
Both power and energy readings are equally affected by changes in the
absorption and/or sensitivity of the thermal disc. Therefore, changing power
calibration changes energy calibration proportionately. In addition, adjusting the
response time of the head can also affect energy calibration. For this reason,
provisions are made to adjust energy calibration without affecting power
calibration.
