8.2.1 LCR Mode
If you set the judgment condition for the comparator (trigger setting is external trigger) and in that
state if a trigger signal is input from the EXT I/O or [TRIG] is pressed in the screen, the judgment
result is output from the signal line for comparator result output of the EXT I/O after measurement
is completed.
Furthermore, if the panel No. has been selected with the panel load signal when a trigger signal is
input from the EXT I/O, measurement is performed after the measurement condition of that panel
No. is loaded.
Examples of the measurement timing:
In the timing example, the valid edge of the TRIG

signal is set to falling (ON).

Whether the judgment results of comparator and BIN judgment are reset when the signal
changes to EOM (HIGH) or updated when measurement is completed, can be selected on the
instrument or by a communication command.
