• To measure current of not more
than 10 Hz, select the AC+DC
mode, and use the [FAST/SLOW]
key to set the response speed to
SLOW .
• Auto ranging will be set. You can
alternatively set manual ranging
(p. 16).
• There may be a delay in the display or output during low-input or low-frequency
measurement.
• When measuring a DC current or generating waveform output with the output
function, align the current direction mark with the direction of current flow in the
conductor and clamp the sensor so that the conductor is located roughly in the
center of the sensor.
