Calibration Value Selection
By storing up to four calibration values in the memory, the desired calibration value can be called to
switch the indicated value. Setting values that can be switched are as follows:
■
Calibration value selection by touch panel
Select "0" - "3" by pressing the / button on the CALIBRATION screen.
When not using, set "0".
■
Calibration value selection by external signal input
With this function, four types of calibration values can be selected with external selector signals
CAL0 and CAL1 (when the calibration value selection setting is external). Set EXT 0 by pressing
the / button on the CALIBRATION screen. According to the input conditions of
external signal inputs CAL0 and CAL1, the display changes as EXT 0 to EXT 3. Normally, when
there is no input to CAL0 and CAL1 (the terminals are open), calibration value 0 is selected. When
each terminal is in the following condition, each calibration value is selected.
CAL1 CAL0 Calibration value
Open Open Calibration value 0
Open Short-circuit Calibration value 1
Short-circuit Open Calibration value 2
Short-circuit Short-circuit Calibration value 3

CAUTION
It takes one second at maximum for
the changed calibration value to
become effective. During this time,
the calibration value is indefinable.
Also, the indicated value is
accordingly indefinable.
