• When the optional "Insulation-Resistance Measurement Range" function is
set to "1: Auto Range", it takes up to 1.5 s to display the resistance value.
When the test finishes before the preset test time, test may end in
.
• When a fixed range is set, “O.F.” will show when the value is beyond the
range’s measurements and “U.F.” will show when the value is lower than the
measurement range.
• During Auto Range evaluation “O.F.”, “U.F.” will be shown when the instru-
ment’s measurement ranges are exceeded.
