Auto Balance Adjustment - KYOWA WGA-120A Instruction Manual

4-5 AUTO BALANCE ADJUSTMENT

The WGA-120A executes the auto balance adjustment as described below;
Push up the BAL/CAL switch 2 times within 0.5 seconds.
Short-circuit the AZ terminal and COM terminal 2 times within 0.5 seconds.
After executing the auto balance adjustment, the WGA-120A outputs the output signal (voltage) 0V. The
WGA-120A outputs the output signal (current) 4mA.
Even if the WGA-120A is turned OFF, the state of the output signal (voltage/current) are maintained to
have the same state before the power OFF.
In order to prevent malfunction, the preferable timings for operating the switch as well as for
short-circuiting the terminal block are described as follows.
5 V
(Open circuit)
