4.CALIBRATION

）

Press the CAL. SELECT button.

）

Select the calibration value from 0 - 3 and determine with the OK button.

4-10-1. External Selection of Calibration Value

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).

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

alibration value 0

Open

Short-circuit

alibration value 1

Short-circuit

Open

alibration value 2

Short-circuit

alibration value 3

COM2

B11

CAL0

B12

CAL1

NOTE

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.
