• When the resistance value exceeds the measurement range, it is displayed as
"O.F." (overflow).
• When the set resistance value does not reach the measurement range, values
are displayed on the "U.F." (underflow).
• You can make the resistance measurement range a fixed range or an auto-
matic range.
See"6.8 Auto-range for insulation-resistance test" (p. 95)
• In fixed range measurements, the upper and lower limit values that can be set
in the respective ranges are the values of the measurement ranges within the
reliable guaranteed range for each of the range.
When it is not possible to get out of the setting screen, the upper-limit value
and the lower-limit value may be out of the ranges shown above. Confirm the
setting value.
