Use the “Hz%” button (11) to switch the display to frequency (Hz) and pulse length
(%). Each press switches the function. Autorange is deactivated. This enables monito-
ring of possible ripple signal (superimposed frequency). In case of pure direct current,
the frequency and % displays are “zero”. Without a measured signal, phantom values
may be displayed. They disappear when a direct current is measured.
Proceed as follows to measure AC voltages “A-AC”:
• Turn the DMM on and select measuring function “A”.
• The table shows the different measuring functions and possible measuring ranges. Select
your measuring range and the respective measuring jacks. The display indicates “DC”.

• Insert the red measuring line into the µA/mA or 10A measuring jack. Plug the black measuring
line into the COM socket.
• Press “MODE” to switch to the AC measuring range. “AC” appears in the display. Pressing
this button again, takes you back etc.
• Now connect the two measuring prods in series to the object to be measured (power circuit,
switch etc.). The measured value is indicated on the display The connection principle cor-
responds to DC measurement.
• After measuring, remove the measuring lines from the measured object and turn the DMM off.
Use the “Hz%” button (11) to switch the display to frequency (Hz) and pulse length
(%). Each press switches the function. Autorange is deactivated.
