Resistance and voltage measurements are judged independently. Both judg

ment results are indicated on the display.
Judgment Operation
The comparator compares measured values with the preset threshold values,
and judges whether the measurement is within the thresholds. Resistance and
voltage measurements are judged independently.
The absolute value of the measurement is compared to the upper and lower
thresholds.
When the absolute value judgment function is on, the absolute value of the mea
-
sured value is compared to the upper and lower thresholds.
Measurement fault values are judged as follows:
PASS/FAIL
Judgment Output
Judgment results (Hi, IN or Lo for both resistance and voltage) are output to EXT
I/O connectors.
Additionally, the instrument can generate PASS/FAIL judgment output to facili
-
tate easy judgments. In this configuration, it outputs a PASS judgment when the
resistance and voltage are both IN and otherwise a FAIL judgment.

Hi (exceeds the upper threshold)

Lo (less than the lower threshold)
With the relative value comparison method (thresholds defined by a reference
value and tolerance), the upper and lower thresholds are calculated internally
for comparison with measurements. Therefore, even if a relative display value
is equal to a judgment threshold (tolerance limit), it may be judged Hi or Lo.
