6 Additional Functions

6.1 Manual ranging

When "AUTO" appears at the top on the left of
the display, the optimum measuring range for a
test function will always be selected automati -
cally.
1) To hold a range selected automatically,
press the button RANGE (1). The indication
"AUTO" will disappear.
2) Each time the button RANGE is pressed,
the next higher range will be selected. Thus,
the resolution of the measured value will de-
crease, however, this will prevent a continu-
ous switch-over in case the measured value
varies between two ranges.
When the highest possible measuring
range is reached, the smallest range will be
selected when the button is pressed again.
If the range is too small, "OL." (overload) will
be indicated.
3) To return to autoranging, keep the button
RANGE pressed for approx. 2 seconds until
"AUTO" reappears on the display or select
another test function with the selector switch
(10).

6.2 Data Hold

It is possible to freeze a measured value indi-
cated on the display. This will allow you, for
example, to still read the value even if the
probe tips have already been removed from
the object to be measured. For this purpose,
press the button HOLD (7). At the top of the
display "HOLD" will appear.
To return to the current measured value, de-
activate the function with the button HOLD
("HOLD" will disappear). The function will also
be deactivated when another test function is
selected with the selector switch (10).

6.3 Relative value measurement

The relative value measurement allows to indi-
cate deviations from a defined measured
value. The function can be activated when
measuring current, voltage, resistance, and
capacitance.
1) Perform a measurement. When the desired
reference value is indicated, press the but-
ton REL (8). At the top of the display, the in-
dication "REL" will appear.
It will not be possible to activate the
function when the display indicates "OL.".
2) When the measured value changes, the de-
viation from the reference value will be indi-
cated.
For relative value measurement, auto -
ranging will be deactivated. Once the meas-
uring range has been exceeded, the display
will indicate "OL.".
3) To deactivate the relative value measure-
ment, actuate the button REL once again. If
required, activate autoranging again with
the button RANGE (keep the button RANGE
pressed for approx. 2 seconds). The relative
value measurement will also be deactivated
when another test function is selected.

7 Replacing the Fuses

If it is not possible to measure currents, check
the internal fuses and have them replaced by
skilled personnel.
WARNING Prior to opening the housing, re-
move the probe tips from the
measuring points and from the
connection jacks, otherwise you
will risk an electric shock.
1) Unscrew the six screws for the housing shell
(two screws are located underneath the tilt
stand) and remove the housing shell.
2) Always replace defective fuses by fuses of
the same type only:
µA and mA range: F500 mAH/1000 V
10 A range:
3) Screw down the housing shell again before
setting the meter into operation.
F10 AH/1000 V
