Calibrating the spectrophotometer
Performing a full calibration
Before using the spectrophotometer for the first time, and once a month thereafter,
perform a full calibration as follows:
1 From the Utilities menu, click Calibrate Spectrophotometer, and Full Calibration.
2 Follow the instructions in the series of message windows that appear, clicking OK
after each message window.
Note For the Black Calibration test, make sure that you measure the dark area until the four vibrating
measurements end completely. This takes approximately 15 seconds.
If the Black calibration successful and the White calibration
successful messages appear on the screen, the full calibration was successful. If
not, repeat this procedure one more time before calling the customer engineer.
Performing the daily calibration
Calibrate the spectrophotometer once a day.
1 From the Utilities menu, click Calibrate Spectrophotometer, and Frequent
Calibration.
2 Follow the instructions in the window that appears.
Note For the White Calibration test, make sure that you measure the white reference area until the
single vibrating measurement ends completely. This takes approximately two seconds.
If the Calibration successful message appears on the screen, the daily
calibration was successful. If not, repeat this procedure one more time before calling
the customer engineer.
