A measured value outside of the accuracy range can also be displayed.

When the measure value is outside of the display range, “Over.F” or “Under.F” is
displayed.
Refer to “9 Specications” (p. 151) for the accuracy range.
IMPORTANT
• The guaranteed accuracy range is different from the display range.
• When the range is set to AUTO, it may take time to display a measured value
immediately after a test starts due to range shift. To check a measured value
immediately, set the range to MANUAL.
(Refer to “3.2 Setting the Range” (p. 36) for the setting procedure.)
• If PASS/FAIL judgment is obtained with a command in the auto range when the
range is not set or before a measured value is displayed, ULFAIL (no judgment)
is returned. Extend the test duration.
• When test terminates without the range having been determined while using
auto-ranging, no measured value will be displayed. Use a longer test time.
• In the auto range, the measured value may uctuate between two ranges. Set
the range to MANUAL.
• “Over.F” (overow) is displayed when the measured value exceeds the display
range maximum value in the auto range and when the measured value exceeds
the maximum display value in each range in the MANUAL range.
• “Under.F” (underow) is displayed when the measured value is less than190 dgt.

range. “Under.F” is not displayed in the
AUTO range.
• The more electrostatic capacitance components the equipment to be measured
contains, the more the measured value uctuates. Also it takes for an output
voltage to rise.
• When the processing is performed at high speed (for example, the test duration
is less than 100 ms), there is a possibility that the voltage monitor cannot be
updated in time. To check the output voltage, monitor the waveform on an
