• In the case of the setting which does not use the
reference point, it is possible to set a preset value for
each of the current value, maximum value and minimum
value measuring mode; for the setting which uses the
reference point, it is possible to set the master values.
• For instructions on setting the preset value, please refer
to "5-2-1. Setting the preset value."

4-3-3. Result evaluation

• Go/No Go test is carried out by comparing data from the
current measuring mode (current value, maximum value,
minimum value, or peak-to-peak value) to the comparator
upper and lower limits.
• This result is displayed on the front panel and output from
the I/O connector (See "7. I/O connector".).
