External Input/output Terminals and Signals
Functions of each signal
Input signal
START (TRIG) When START (TRIG) signal is switched from OFF to ON, measurement is performed
once on the edge.
This is only effective when TRIGGER SOURCE is set to the external [EXT] side.
0ADJ_ALL When the 0ADJ_ALL signal is switched from OFF to ON, all zero adjustment (p. 26)
is performed once on the edge.
STOP When the STOP signal is switched from OFF to ON, the measurement is interrupted
on the edge.
0ADJ_SPOT When the 0ADJ_ALL signal is switched from OFF to ON, spot zero adjustment
(p. 26) is performed on the edge.
CAL When the CAL signal is switched from OFF to ON in the self-calibration manual
setting, the self-calibration is started on the edge. When self-calibration is set to auto,
the above is ineffective.
Self-calibration takes approximately 210 ms. When a switch is input during
measurement, self-calibration is performed after the measurement.
LOAD0 to LOAD6 When the number of the panel to load is selected and the TRIG signal is input, the
selected panel number is read and measured. LOAD0 is LSB and LOAD6 is MSB.
When the TRIG signal is input, if LOAD0 to LOAD6 are the same as the previous
ones, the panel load is not performed. In the above case, when the external trigger
is used, the measurement is performed once as a normal TRIG signal. When the
internal trigger is used, the input of LOAD0 to LOAD6 is ineffective.

* When turning all of the LOAD0 to LOAD6 to ON or OFF and then the START
(TRIG) signal to ON, the panel loading is not performed.
• In the case of setting to the external trigger, the measurement is performed once
after the completion of the loading.
• In the case of setting to the internal trigger, panel loading will not be performed.
