to 1000 V DC or 750 V AC rms max. Exercise particular care when
dealing with voltages in excess of 25 V AC or 35 V DC.
Warning!
Never exceed the maximum input values because this could
damage the measuring appliance and poses risk of fatal injury.

5.3 Initial use

5.3.1 Basic settings

Important
The following text contains figures in brackets. These figures
relate to the Description of Controls under heading 4.
Press the ON button (1). To select a measurement type, set the
rotary switch to the desired position.

5.3.2 Button assignment

a) The ON/OFF button (1) switches the multimeter both on and
off: pressing this button once switches the appliance on, press-
ing it again switches the DMM off.
b) „=/~ Ω/•)" (2) toggles from AC (alternating current or voltage)
to DC (direct current or voltage) and vice versa and from res-
istance measurement (omega) to continuity testing (sound
symbol) and vice versa.
c) „R-H" (3) When this button is pressed once, the "R-H" symbol
(Range Hold) appears on the display and the "auto range"
function (= automatic range selection) is no longer active. Each
subsequent press on this button increases the measuring range
in the case of voltage measurement or decreases the meas-
uring range in the case of resistance measurement. The chan-
12
ge in range can be recognised firstly by the change in the unit
of measurement and secondly by the position of the decimal
point. To return to automatic range selection, press the "R-H"
button for longer than roughly 1 s. The "R-H" symbol then dis-
appears from the display.
5.3.3 Receptacle or socket assignment
a) Transistor receptacle hfe
The 8-pole transistor receptacle has symmetrical legends. Plug
the base (B), emitter (E) and collector (C) transistor terminals
into the receptacle sockets as shown. The pin assignment of
various transistors can be found in a transistor Data Book.
b) Receptacle for temperature measurement(s) and capacitance
measurements
To measure a temperature, plug the terminals of a type K tem-
perature probe (NiCrNi) into the marked sockets ensuring that
the polarity is correct. Make sure that the narrow blade
contact is inserted in the narrow slit contact and the wide
blade contact is inserted in the wide slit contact. A connector
that is the wrong way round will not fit in the receptacle.
Insert a discharged (!) bipolar capacitor in the outer contact slit
of the test socket. Make sure that the leads are long enough
and not too thick, otherwise this may cause faulty measure-
ments.
Warning!
The inner contacts are for temperature measurements and the
outer contacts are only for measurements on capacitors up to
400 nF max. Never get the sockets mixed up because this will
damage the multimeter. Note the diagram below:
