Digital Zero by means of the external signal "D/Z input"
The instant when D/Z and COM2 of the input/output connector are short-circuited from an open
state (ON edge), Digital Zero functions to zero both the ch1 value and ch2 value at one time.
For executing Digital Zero for the ch1 value and ch2 value individually, see "5-5.D/Z
synchronous mode" on page 39.
5-5.
D/Z synchronous mode
In execution of Digital Zero by means of the external input signal, Digital Zero can be executed for
the ch1 value and ch2 value individually or at one time.
≪
Setting value

0
：
ch1 and ch2 synchronous When the external input "D/Z-1 (B11) is turned ON,
Digital Zero functions on both ch1 and ch2 at the
same timing.
1
：
ch1 and ch2 independent When the external input "D/Z-1 (B11) is turned ON,
Digital Zero functions on ch1, and when the external
input "D/Z-2 (B12) is turned ON, Digital Zero
functions on ch2.
