seconds and switch on the clamp meter at the same time. The symbol disappears. Restart after
switching off the meter, the automatic switch-off can be restored.
Auto-ranging
The meter automatically selects the measuring range that is best suited for the measurement
performed. The measuring unit and resolution are adjusted at the same time.
AC Zero Input Behavior of True-rms Meters
Unlike averaging meters, which can accurately measure only pure sinewaves, True-rms meters
accurately measure distorted waveforms. Calculating True-rms converters require a certain level
of input voltage to make a measurement. This is why ac voltage and current ranges are specified
from 5 % of range to 100 % of range. Non-zero digits that are displayed on a True-rms meter when
the test leads are open or are shorted are normal. They do not affect the specified ac accuracy
above 5 % of range.
Connecting Test Leads
Do not test if leads are improperly seated. Results could
cause intermittent display readings. To ensure proper
connection, firmly press leads into the input jack completely.
