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.
If you did the
Warming-Up and Pre-Calibration section successfully and you want to store the
Pre-Calibration data before continuing with the Final Calibration:
1. Press
4
(YES).
When you turn off and turn on the Test Tool again, it will show the message:
The instrument needs calibration.
Please contact your service center.
The calibration date and number do not update. You must continue with the Final
Calibration.
To return to the Maintenance mode and repeat the complete calibration:
1. Press
3
(NO).
2. Press
1
until the display shows:
WarmingUp (CL 0200):IDLE
3. Calibrate the Test Tool, starting at Warming-Up and Pre-Calibration .
If you want to exit and maintain the old calibration data:
1. Turn off the Test Tool.
Final Calibration
Before you start the final calibration, do the Warming-Up and Pre-Calibration section.
The final calibration requires input conditions that are described in each step. After a step
starts, steps that require the same input conditions are done automatically. For example, if you
start calibration step CL 0850, the calibration can include step CL 0869 and at the end the
display shows CL 0799: READY.
Note
You must always start the calibration adjustment at the WarmingUp (CL 0200) step.
The calibration will be invalid if you start at any other step. See the Warming-Up 2,
Warm-Up Final, and ADC Timing section.
If you do calibration step N (for example, step CL 0581), then return to a previous step (for
example, step CL 0580), and then calibrate this step, the complete final calibration becomes
invalid; then you must repeat the calibration starting at the Warming-Up 2, Warm-Up Final, and
ADC Timing section.
You can repeat a step that shows the status :READY by pressing
3
again.
Refer to Table 14 for all calibration steps for each function.
