4.5 PASS or FAIL Determination
______________________________________________________________________________________________
NOTE
When the optional "Insulation Resistance Measurement Range" function is set to
"
1
: Auto Range", it takes up to 1.3 s to display the resistance value. When the
test finishes before the preset test time, the test results in a
LOWER FAIL
.
Setting an upper-limit value while using a fixed range restricts the range of
resistance that can be measured. Therefore, even if a resistance value lower than
the preset upper-limit value is measured, "
O.F.
" is displayed resulting in an
UPPER FAIL.
See Section 4.3.2
Flow of FAIL determination
1.
Press the START key to start a test.
2.
A voltage continues to be output until the test time elapses and measure
resistance.
3.
When the preset test time has elapsed, and the measured resistance value
deviates from the upper- or lower-limit value, the unit stops outputting a
voltage and switches to the FAIL state.
FAIL
lights up in the FAIL state
together with
LOWER
or
UPPER
.
