8.DIGITAL ZERO FUNCTION

8. DIGITAL ZERO FUNCTION

This function zeros the indicated value.

Digital Zero by Key Operation

Digital Zero by External Signal Input

At the instant when the digital zero input (A5) and COM (A6) on the signal
input/output terminal block at the back are short-circuited, the digital zero
function works to zero the indicated value.

Perform digital zero.

When the indicated value becomes zero, digital zero is completed.

ZERO

Digital zero

OFF

Turn ON for 5 msec or more.

• The digital zero function does not work if the calibration

LOCK is OFF.

It works only when the calibration LOCK is ON.

Also, the digital zero function is reset when the power is

turned off.

• For the connection of the digital zero input terminals, see

"Connecting Hold and Digital Zero Signals" on page 19.
