7.12 Limit Function
This function defines the segment for the measurement data, sets the upper limit and the lower limit
for the segment, and judges pass/fail comparing with the data.
The limit can be set in each channel (CH1 and CH2) and in each sub-measure screen (CH3 and
CH4) independently.
How to output the pass/fail judgement is as follows.
•
PASS or FAIL is displayed on the screen.
•
The beep can be set. When the limit test passes or fails, the beep sounds.
•
Displays the trace in the Fail section with red.
•
In the case of fail, sets Limit Fail Summary-Bit of Questionable Status Register.
•
In the case of fail, set LOW Status on the parallel I/O port of the rear panel.
