tions.
To select such an additional function, press the FUNCTION (2) button.
By the repeated pressing of this button the various subfunctions are
displayed in the display. To exit from the menu, press the Set/Reset but-
ton twice: once sets the subfunction, twice resets it.
C.2 Button configuration
a) The ON/OFF button switches the measuring instrument both on and
off: if the button is pressed once, the instrument is switched on; if
it is pressed a second time, it is switched off.
After approx. 8 minutes of "zero use", when the display hardly
changes (with open test leads), the Auto Power Off function swit-
ches the multimeter off, to save energy. The multimeter must then
be switched off and on again.
b) FUNCTION
The A-H symbol appears in the display as soon as the instrument is
switched on. Press the "FUNCTION" button to call the subfunctions.
The following symbols appear in the display as a result: D-H -> MIN
-> MAX -> REL -> CMP -> R-{783}H -> EXT -> MEM -> RCL
c) Set/Reset
To activate, i.e. switch on, a selected subfunction, press this button
once.
Press the button once to return to the basic setting again (Reset).
d) DC/Ohm/AC (•)
When the operating mode switch is set to voltage or current mea-
surement, press this button to switch from DC voltage measurement
to AC voltage measurement. When the measurement function
switch is set to (•), this button must also be pressed to switch from
acoustic continuity test to resistance measurement.
e) UP / DOWN
Press one of these buttons to set the reference value in the REL or
CMP subfunctions and to address the stored value in the MEM or
RCL (Recall Memory) subfunctions.
C.3 Connector and socket configuration
a) Sockets for capacity or inductance measurement
Insert the (discharged!) capacitor observing polarity or the voltage-
free inductance (coil) into the sockets. Ensure that the connections
are long enough, because otherwise incorrect measurements can
28
occur.
b) Operating mode switch = measurement function switch (8)
Attention!
The operating mode switch may not be moved during measurements,
because otherwise the measuring instrument can be destroyed and as a
result danger to life can occur.
Arranged in a semi-circle, the various basic measurement ranges selecta-
ble by rotating the switch are:
mV
=
millivolt AC/DC (milli = 10 exp.-3)
V
=
Volt AC/DC
400mA =
milliampere AC/DC
20A
=
Ampere AC/DC
(@)
=
Continuity test
W
=
Resistance measurement
mH
=
Inductance measurement
CAP
=
Capacity measurement
LOGIC
=
Logic test
c) 20 A socket
For DC or AC current measurements up to 20 A max.(!), the red test
lead must be plugged in here.
Attention!
When measuring current,the operating mode switch must never be set
to voltage (mV or V) or to any other switch position other than current
measurement (mA or A).
d) mA socket
The red test lead must be plugged in here for DC or AC current
measurements to 400 mA max!, but only when the operating mode
switch is set to "400mA".
e) COM = common socket
Except for capacity and inductance measurements, the black test
lead must be plugged in here for all measurements (common socket
means minus, "-" or ground socket)
f) V/Ohm socket
