Comparator results are displayed here using large characters, primary and secondary test
results are displayed in this area as small characters.
In the lower half of the screen, some settings related to comparator are displayed in this area.
4.2.1 Comparator Function ON/Off [COMP]
The built-in comparator can sort devices into 9 sets of primary parameters and 1 set of
secondary parameters, and classify them into up to 10 kinds of bins (BIN 1~BIN 9 and OUT OF
BIN). In addition, a device which primary parameter is within limits, but secondary parameter
is not, can be sorted into an auxiliary BIN (AUX).
The comparator is allowed to be turned off.
