d) UP/DOWN
Press UP or Down button to determine the reference value in the fun-
ction modes REL or CMP or to address the stored value (reference
numbers) in the subfunctions MEM or RCL (recall memory).
4.3.3 Terminal and Switch Imprint
a) Transistor Socket hfe
The eight pole transistor terminal is lettered symmetrically with (E)
Emitter,(B) Base, (C) Collector. Insert the transistor pins into the tran-
sistor socket as in the drawing according to transistor type, remove
voltage before measurement.
b) Capacity- and Temperature Measuring Socket (poles "+" and "-") and
signal output S/O.
In this socket discharged capacitors can be checked, observe correct
polarity. Make sure the connector pins are long enough to avoid
unreliable measurement .
For temperature measurement plug in type "K" temp probes (NiCrNi)
in the marked sockets, observe the correct polarity. To receive an out-
put signal connect the respective adapter with the CAP-socket.
Attention!
The outer contacts are only for capacitance measurement, the inner con-
tacts are only! for temperature measurement. Never confuse the sockets
to avoid damage to the meter. Pay attention to the following picture:

Attention!
Never turn the rotary function switch during measurement, as there is

the risk of instrument damage and danger to life if there are voltages
exceeding 25 VAC or 35 VDC.
The different basic measuring ranges are selectable by turning the
switch:
DCV = DC voltage (blue, 5 ranges)
ACV = AC voltage (red, 5 ranges)
ACA = AC ampere (red, 3 ranges)
DCA = DC ampere (yellow 3 ranges
hFE = transistor test (grey, 1 range)
LOGIC = logic measurement (grey, 1 range)
CAP = capacitance measurement (grey, 2 ranges)
FREQ = frequency measurement (grey, 1 range)
TEMP = temperature measurement (yellow, 1 range)
S/O = Signal-Out (red, "1" range)
/ = diode test/acoustic continuity test (blue, 1 range)
Ohm = resistance measurement (blue, 6 ranges)
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 never be
set to voltage measurement (mV or V).
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".
f) COM = Common Input Terminal
For all measurements, except capacity and transistor measurement or
"S/O" function, the black test-lead must be connected. (common-ter-
minal means minus or "-" or earthing jack)
