Figure 5-2. Display Test Pattern
5.5 Warming Up & Pre-Calibration
After entering the Warming-Up & Pre-Calibration state, the display shows:
WarmingUp (CL 0200):IDLE (valid) or (invalid).
You must always start the Warming Up & Pre Calibration at
Warming Up (CL0200) .
Starting at another step will make the calibration invalid!
Proceed as follows:
1. Remove all input connections from the test tool.
2. Press
to start the Warming-Up & Pre-Calibration.
The display shows the calibration step in progress, and its status.
The first step is
WarmingUp (CL0200) :BUSY 00:29:59 . The warming-up period is
counted down from 00:29:59 to 00:00:00. Then the other pre-calibration steps are
performed automatically. The procedure takes about 60 minutes.
3. Wait until the display shows End Precal :READY
4. Continue at Section 5.6.
5.6 Final Calibration
You must always start the Final Calibration at the first step of Section 5.6.1. Starting at
another step will make the calibration invalid!
If you proceeded to step N (for example step CL 0615), then return to a previous step
(for example step CL 0613), and then calibrate this step, the complete final calibration
becomes invalid. You must do the final calibration from the beginning (step CL 0600)
again.
You can repeat a step that shows the status
:READY by pressing again.
