Using Correction Factors (CFs)
This feature is available only when you are using NORM calibration mode (page 13).
Using CF Correction
The CL-200 CHROMA METER allows you to set correction factors (CFs) that can be applied
to your measurement results. You can use this feature to correct for disparities among differ-
ent CL-200s or to adjust calibration arbitrarily as needed. After setting the CFs, you can use
the [
CF ] key to switch use of CF correction ON or OFF.
Setting the CFs
You set the CFs in two stages: First you measure a light source whose output values are
known, and then you key in the known values. The CHROMA METER calculates the CFs
based on the differences between the measured values and the keyed-in values. The CHROMA
METER stores the CF settings in nonvolatile memory, so that these values are retained even
when you switch off the power or change the batteries.
To set the CF values, follow the steps below.

dinates.
2. Set the HOLD button to the RUN position (pop the button out),
and take a measurement of the light source.
