Press the
to choose a current range.
• Choose a current range with a maximum peak
current higher than the peak value of a current under
measurement.
See "Maximum peak current" (p. 7 2).
If the peak value of the current under measurement
exceeds the maximum peak current of the chosen current
range, the output waveform will be saturated or distorted,
preventing you from correctly observing the current
waveform.
• You need to choose a current range according to the level
of the current under measurement to minimize an adverse
effect of noise on observation of the current waveform. The
following table shows the recommended current ranges for
each of the levels of currents under measurement.
