Warming-Up and Pre-Calibration

The Warming-Up and Pre-Calibration state is entered after the calibration mode,

or after selecting the next step if you have done the Contrast Calibration step,

CL 120. The display will show

WarmingUp (CL 0200):IDLE (valid) or (invalid).

Unless you want to calibrate the display contrast only, you must always start the

calibration adjustment at the

WarmingUp (CL 0200) step. Starting at another step

will make the calibration invalid.

The Warming-Up and Pre-Calibration consists of a 30 minutes warming-up

period, followed by several internal calibration adjustment steps that do not

require input signals. The total process takes about 75 minutes.

To do the Warming-Up and Pre-Calibration:

1. Remove all input connections from the Test Tool.

2. Press

to start the Warming-Up and Pre-Calibration.

The display shows the calibration step in progress and its status.

The first step is

WarmingUp (CL 0200) :BUSY 00:29:59 or WarmingUp1

(CL 0200) :BUSY 00:09:59

. The warming-up period is counted down to

00:00:00. Then the remaining pre-calibration steps are performed

automatically. The entire procedure takes about 60 minutes.

3. Wait until the display shows

End Precal: READY.

The PreCal data have now been stored in FlashROM.

If you turn off the Test Tool now by accident, turn it on again immediately and

select the calibration mode. Continue with step 5 below.

4. Press

(NEXT) several times, see Final Calibration.

If you turn off the Test Tool now, and you do not turn on immediately, the

Test Tool has cooled down, and you must repeat the Warming-Up and

Pre-Calibration (select the calibration mode and start at CL 0200).

5. Press

(NEXT) and continue at the Final Calibration section.

Error Messages

If error message 1000 is displayed during Warming-Up or Pre-Calibration step

CL 0215, the Main PCA hardware version is not suitable for the installed software

version. Other error messages during Warming-Up or Pre-Calibration indicate

that the Test Tool is defective, and should be repaired.
