Measuring Leakage Current
Displaying the frequency (Hz)
When [SLOW] is displayed:
[SLOW]
[Hz]
[RMS]
The frequency of the current being measured
will be displayed.
If there is no input, or input is lower than 30 Hz,
"----" will be displayed.
• Enable the lter function when conducting measurement in
the cases below (p. 35).
(1) If meaningless data is displayed due to noise.
(2)
If you use the instrument to measure the waveforms on the
secondary side of an inverter, or other special waveforms.
• The instrument may not be able to perform measurement in
the cases below.
(1)
If the input current is 1/10 or less of the current range (full-
scale).
(2)
If you measure high frequencies with the lter function
enabled.
• The frequency range is set automatically. If you press the
RANGE key, only the current range will be changed.
