reached while measuring, the indication will
be updated accordingly.
3. “MAX/MIN” (flashing): The digital display will
show the present reading.
To deactivate this function, keep the button
“MAX/MIN” pressed for approx. 2 seconds.
The automatic range selection will be reacti-
vated (“AUTO” will be displayed).
To reset the values in order to perform a new
MIN/MAX measurement, deactivate and reac-
tivate the function.
7.4 Indicating short peaks
When measuring voltages (
¿
/~) and currents
(
¿
/~), the PEAK function will allow to indicate
peak values occurring too shortly to be
recorded during the MAX/MIN measurement
(
chapter 7.3), e. g. short interfering pulses.
It will be possible to measure peaks of a dura-
tion ≥ 1 ms.
1) When measuring voltages or currents, wait
until the reading on the display has stabi-
lized.
2) Keep the button “PEAK” (7) pressed until
“CAL.” is displayed: A calibration will be per-
formed.
3) After calibrating, press the button “PEAK”.
The digital display will indicate the positive
peak value of the measurement (“P
MAX
”).
The automatic range selection will be deac-
tivated (“MANU” will be displayed).
When the button “PEAK” is pressed
again, the indication will change to the neg-
ative peak value of the measurement
(“P
MIN
”).
If a higher or lower peak value is reached
while measuring, the corresponding indica-
tion will be updated.
4) Use the button “PEAK” to switch between
“P
MAX
” and “P
MIN
”.
5) To deactivate this function, keep the button
pressed for approx. 2 seconds until “P
MAX
”
or “P
MIN
” disappears. The automatic range
selection will be reactivated (“AUTO” will be
displayed).
Note: If you select another measuring function
with the selector switch (10) after calibrating,
repeat the calibration for the new measuring
function.

Inserting a New Battery
or Replacing Fuses
8.1 Inserting a battery
If nothing is displayed or if the symbol
(= low
battery) is displayed, insert a new 9 V battery.
1) Fold up the tilt stand on the rear side of the
meter and release the two central screws of
the battery compartment cover.
2) Remove the cover and insert a 9 V battery
as indicated in the compartment.
3) Close the battery compartment and fasten
the battery compartment cover.
8.2 Replacing fuses
If it is not possible to measure currents, check
the internal fuses and have them replaced by
qualified personnel.
1) On the rear side of the meter, release the six
outer screws (two screws are situated under
the tilt stand) and remove the rear housing
shell.
2) Replace defective fuses by fuses of the
same type only:
µ
A and mA range: F 500 mAH/1000 V
10 A range:
F 10 AH/1000 V
3) Reassemble the housing shells and tightly
fasten the screws.
Used batteries must not be placed in
the household waste, always take
them to a special waste disposal, e. g.
collection container at your retailer.
WARNING
Before opening the housing, re-
move the test tips from the
measuring points and the test
leads from the jacks on the
meter, otherwise you will risk an
electric shock. Never operate
the meter when it is open.
