Restoring Factory Calibration
The C401/301/201/101/102/103/104/105 Colorimeter allows you to reset
the meter back to the factory default calibration values. This feature is
extremely useful when there are errors in calibration or when you have
new calibration standards.
1. With the meter switched off, press MODE and ON/OFF keys
simultaneously for about 2 seconds.
2. The meter will momentarily flash the model number and [URST] (User-
Reset) and then display [No].
3. Use MODE key to select (toggle) between [YES] or [No].
[YES] = To restore meter back to factory calibration values
[No] = To retain last calibrated values
4. After selecting [YES] or [No], press READ/ENTER key.
5. The meter will now flash the model number, the meter’s revision
number and enter the measurement selection mode.
Figure 9 shows the sequence for restoring factory calibration values.
