comparison
In Waveform & Displacement Comparison, when displacement (indicated value)
changes suddenly, or displacement (indicated value) has not been updated for
some time, turn the ERROR signal ON.
For details, refer to「12-3. Waveform & Displacement Comparison」.
Be ON when the indicated value and comparison result have been finalized.
Please use it when reading the output signal.（Details according to each timing
chart)
The common output terminal of terminal No.1 to 7 (OUT1 to 5, Error, SYNC).
For details, refer to「3-4. 4) Each output equivalent circuits」
Control terminal of Start / Peak hold action of Ach. (ON ("0") trailing edge is
active)
For details, refer to「11. Hold Function (Hold)」.
：Start / Peak hold Bch (STB)
Control terminal of Start / Peak hold action of Bch. (ON ("0") trailing edge is
active)
For details, refer to「11. Hold Function (Hold)」.
The terminal of turning the indicated value to 0 for Ach. (ON ("0") trailing edge
is active)
For details, refer to「4-6. Functional Description (9)」and「12-3. Waveform &
Displacement Comparison」.
The terminal of turning the indicated value to 0 for Bch. (ON ("0") trailing edge
is active)
However, if Waveform & Displacement Comparison is chosen by meter setup in
the basic function setting, it is denied.
For details, refer to「4-6. Functional Description (9)」and「12-3. Waveform &
Displacement Comparison」.
The common input terminal of terminal No.9 to 12 (STA, STB, DZA, DZB).
