f) COM = Common Input Terminal
For all measurements, except capacity, temperature and transistor
measurement, the Black test-lead must be connected. (common-ter-
minal means minus or “-“ or earthing jack)
g) V/Ohm-Socket
For measurement of voltage, frequency, resistance, continuity, diodes
and logic tests plug in the Red test-lead in this terminal.
h) For power measurement insert in all sockets the measuring adapter.
4.4.4 Display Explanation and Symbols
a) Digital Display
Digital readings are displayed the main- and the sub-displays (small
displays) on a 4000-count basis (“3999“) with automatic polarity indic-
tion (-) (for negative voltage or reversed polarity). There are three
decimal point positions.
b) Analogous Bargraph
The bargraph consists of 43 segments and is faster than the digital
display. It functions as the needle of an analogous measuring instru-
ment, but without its mechanical disadvantages. Is is especially for
quick changing measuring signals, for which the digital display is too
“slow“. So you can quickly see tendencies in the measuring values.
If the measuring range is exceeded “OL“ for Overload is displayed the
bargraph is flashing and a warning sound is emitted (no acoustic sig-
nal during measurement of resistance, diode, temperature - “OL“
without thermo-element).
c) Data-Hold “D-H“
In this mode you can freeze a reading in the second (“small“) display
by pressing the SET/R button.
d) Range Hold “R-H“
In this function you can switch off the automatic range selection
(Auto Range) and set the measuring range manually. Each time the
UP or DOWN button is pressed the decimal point is moved one posi-
tion to the left or to the right, the units of measure are changed res-
pectively (e.g. from kHz to MHz during frequency measurement). To

LOGIC
= Logic Test - no function mode possible
/Ohm
= acoustic continuity test - no Auto-Range during continuity
test, in the resistance measuring range Auto-Range and
manual range selction (R-H) is possible
= diode test - no R-H possible
CAP
= capacitance measurement, A-R and R-H is possible
hFE
= transistor test - no R-H possible
TEMP
= temperature measurement in °C - no R-H possible
4 mA
= DC and AC current measurement to max. 4 mA - A-R and R-
H possible
400 mA
= DC and AC current measurement to max. 400 mA - A-R and
R-H possible
20 A
= DC and AC current measurement to max. 20 A - A-R and
R-H possible
POWER
= power measurement in [W] = Watt = unit for real power
d) 20-A-Input Socket
For DC- and AC-current measurements to max. ! 20 A. Insert the Red
test-lead into the input socket.
Attention !
During current measurement the rotary function switch must not be set
to voltage measurement (mV or V or other positions than 4 mA, 400 mA,
20 A).
e) mA-Measuring Socket
For measurements to 400 mA max.!, connect the Red test-lead, pay
attention that the rotary function switch is set to position “4 mA“ or
“400 mA“.
