Conrad VC 350E Mode D'emploi page 7

The measuring instrument has a special function which enables
the built-in fuses to be checked before each measurement for
soundness (whether "blown" or intact). For this, proceed as follo-
ws:
- Position the rotary switch to "
test)
- Press the yellow button once. The word "FUSE" appears in the
display.
- Connect "only" the red measuring lead to the V/Ohm/F socket
of the multimeter.
- Touch the metal insert of (deep within) the uA/mA socket with
the probe). Should an acoustic signal sound and the bar graph
indicate a minimum, the fuse (800 mA, quick-acting) is in
order. In case not, the fuse is defective. In this case, replace the
fuse with new.
- Next, touch the metal insert of (deep within) the A socket with
the probe). Should an acoustic signal sound and the bar graph
indicate a minimum, the fuse (20A, quick-acting) is in order. In
case not, the fuse is defective. In this case, replace the fuse
with new.
5.2 Connecting the instrument leads
Always use only the supplied measuring leads for making measu-
rements. Before each connection note the condition of the
connecting plug and test prods and check the insulation for dama-
ge. These measuring leads are intended for voltages up to 1500 V
max. The measuring instrument, the VC 350E is designed for vol-
tages up to 1000 VDC or 750 VAC rms max. Take particular care
when dealing with voltages greater than 25 V AC or 35 V DC.

/ " (Continuity check/Diode
Attention!
Never exceed the input levels, as in this can cause damage to the
measuring device, and can endanger the user.
5.4 Positioning the measuring instrument (sloping position) or
position of use Always operate the multimeter so that the
liquid crystal display (LCD) can be read and the digital
display is facing upwards. There is a fold-out bracket on the
rear of the instrument for better readability in upright
operation.
5.4 Commissioning
5.4.1 Basic settings
The measuring instrument is switched on by turning the rotary
switch to the desired measurement function. "Normal" measure-
ments can now be carried out without additional functions.
To select such an additional function, operate one of the buttons
in the button panel.
5.4.2 Connector & socket configuration and switch markings
a) Connector for capacity and temperature measurement (polari-
sed "+" and "-")
Place a (discharged!) capacitor correctly polarised in the sockets.
Ensure that the connections are long enough, because other-
wise incorrect measurements can occur.
For temperature measurement plug the connections of a K-type
thermocouple element (NiCrNi) with the correct polarity into
the marked sockets.
b) Type of operation switch = measurement function switch (10)
