5. OPERATING INSTRUCTIONS
When press
key to trun on the meter, the various settings
depend on the condition the meter was in before it was last
turned off.
5-1 Setting the Calibration Factor
Because the meter of the photopic filter is not perfect and small
adjustments to the collected radiation profile are needed to
improve the meter accuracy when measuring LED’s. These
adjustments are dependent on the peak wavelength and spectral
bandwidth of the test LED emission. The meter frimware makes
corrections to the photometric data through a user entered
calibration factors. If the test source is not an LED, the calibration
factor entry should be “1.00”.
1. Press
key to turn on the meter.
2. Press
key first then press
key to enter the
calibration factor setting mode.
3. Press
key to set to the desired calibration factor value.
4. Press
