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 monitoring of
possible ripple signal (superimposed frequency). In case of pure direct current, the fre-
quency and % displays are “zero”. Without a measured signal, phantom values may be dis-
played. 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 mea-
suring range and the respective measuring jacks. The display indicates “DC”.

µA <4000 µA COM + mAµA
mA 4mA– 399 mA COM + mAµA
A 400 mA– 10 A COM + 10A
- Insert the red measuring line into the µA/mAor 10Ameasuring 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 but-
ton 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 corresponds to DC
measurement.
- After measuring, remove the measuring lines from the measured object and turn the DMM off.
