Calibration and Adjustment
Aborting a Calibration in Progress
Sometimes it may be n ecessar y t o abor t a calibr ation after t he p r oced ur e
has alr ead y been in itiat ed. You can abor t a calibr ation at any time by
tu r n in g off th e p ower. You can abor t a calibr ation by issu in g a r emote
in ter face d evice clear message.
Adjustment Procedures
You can ad just both t he gain an d offset for each r an ge on ever y chan n el.
Op tion ally, you can choose t o ad ju st on ly t he offset for each r an ge on
each chan n el. A fu ll adjustmen t r equ ir es you p er for m both th e gain an d

If you abort a calibration in progress when the digitizer is attempting to write new
calibration constants to EEPROM, you may lose all calibration constants. Typically,
upon re applying power, the digitizer will report an error You should not use the
digitizer until a complete re adjustment has been performed. A list of the possible
calibration errors is given on
