The following operations are possible when BCD
input/output terminal is used.
Input : Comparator value selection (4 settings),
measuring mode (current value, maximum value,
minimum value, peak-to-peak values) selection
Output : 6 digits
Outputs one of the current, maximum,
minimum, and peak-to-peak values selected
via the keys on the front panel and the
external input.
