• Turn the digital multimeter on and select the measuring range “A
” with the rotary switch (5). The values on the rotary switch (5)
indicates the maximum measurement value of that selection. Try to
start measuring with the largest measuring range if possible, because
the fine fuse will trigger in case of excess current.
• Plug the black measuring lead into the COM socket. Insert the red
measuring lead into the 10A max current measuring socket (10)
(with currents > 200 mA) or into the mAμA socket (8) (with currents
<200 mA).
• Now connect the two test prods in series with the object to be
measured (battery, circuit etc.); the display indicates the polarity of the
measured value together with the currently measured value. The unit
of the measurement is µA, mA or A (depends on the measuring range
selected).
• After measuring, remove the measuring leads from the measuring
object. Switch off the power supply before disconnecting test leads,
especially important when measuring large currents. Then turn the
digital multimeter off. Turn the rotary switch (5) to the position “OFF”.

Proceed as follows to measure AC currents “µA, mA, A”
Always start current measurements at the highest measurement range and switch down to lower ranges if
necessary. Before changing the measurement range, always power down the circuit. All current measuring
ranges are secured with fuses and thus protected against overload.
• Turn the digital multimeter on and select the measuring range “A” with
the rotary switch (5). The values on the rotary switch (5) indicates the
