3.3 Measuring Frequencies
During voltage/current measurement of AC, the frequency can
be checked in the sub display. It is not possible to change the
frequency range.

Frequency
• If signals out of the range of frequency measurement are measured,
[-----] appears. Be aware of it.
• The sensitivity of the frequency measurement is regulated by range.
(Minimum sensitivity voltage (p. 92), Minimum sensitivity current (p. 92))
When the value is less than the minimum sensitivity voltage (current),
the indicated value may uctuate. When the voltage (current) range is
lowered, the value stabilizes. This does not apply to cases where the value
uctuates due to noise.
• During the measurement of low frequency, if the auto range does not
stabilize and frequency cannot be measured, x the range and measure
again.
