Forced Zero (Zero-shift) Section 2-5
2-5 Forced Zero (Zero-shift)
The forced zero function enables the Unit to shift the scaled conversion data
to 0 to calibrate, which allows relative object measurement with ease.
The forced zero state stays in effect until ZERO RESET input signal to the
Unit is turned ON.
When zero input is turned ON while the Unit is sampling data, the scaled con-
version data will be shifted to zero and stored as binary data in the input word,
or the comparison result flags of the input word are turned ON or OFF accord-
ing to the comparison result processed by the Unit.
The nonvolatile memory can store the zero shift value.
While the forced-zero state stays in effect, the ZERO indicator is lit.
Note The forced zero function is not effective when the timing hold mode is set to
peak-to-peak hold.
2-6 Voltage Monitor Output
The CQM1-LSE02 has a voltage monitor output function.
Scaled conversion data monitor mode or set data D/A output mode can be
selected.
The Unit refreshes its monitor output at 0.5-s intervals.

In this mode, it is possible to output voltage corresponding to the scaled con-
version data.
