Keys Used in the Calibration Steps
The Tester keys behave as follows when you do the calibration adjustment procedure:
Tstores the calibration value and advances to the next step.
H ignores the calibration value and advances to the next step. H is also used to exit the
calibration function after the calibration adjustment sequence is complete.
Calibration Adjustment Procedure
Use these steps to make calibration adjustments to the Tester. If the Tester is turned off
before completion of the adjustment procedure, the calibration constants are not changed.
