■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.
4-4. Excitation Voltage
Select the bridge voltage supplied to the strain gauge sensor.
The bridge voltage can be selected from 2.5V and 10V.
After this setting, be sure to perform calibration.
How to set
4-5. Unit
Set the unit of the values displayed. For settable units, see the "Unit Setting List"on page 91.

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

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
