Proceed as follows to measure alternating currents (A):
Switch the multimeter on and select "10A, mA, or µA" mode. Press the "SE-
LECT" button to switch to AC mode. The display shows "
LECT" button again to switch back to DC mode.
Connect the multimeter to the corresponding measuring inputs and the measur-
ing circuit as described in "DC measurement" and follow the steps below.
11.7 Measuring frequency/duty cycle in %
The multimeter can be used to measure the frequency of a signal voltage (supports
frequencies from 10 Hz to 10 MHz). The maximum input is 20 Vrms. This mode is
not suitable for taking measurements on mains voltages. Observe the input specifi-
cations in the technical data.
Proceed as follows to take a frequency measurement:
Switch on the multimeter and select
"Hz" mode. "Hz" appears on the
display.
Plug the red test lead into the Hz
measurement socket and the black
test lead into the COM measure-
ment socket.
Connect the two test probes to the
object that you want to measure
(e.g. signal generator or circuit).
The frequency and corresponding
unit will be indicated on the main
display. The sub-display will show
the pulse ratio of the positive half-
wave in %. Pressing the "SELECT"
button toggles the "Hz/%" display.
After measuring, remove the test leads from the measured object and turn the
multimeter off.
