Using The Multimeter - Conrad VC 350E Bedienungsanleitung

6. COM (-) input socket (COM- or negative connection)
7. V-Ohm-(+) input socket (= positive connection)
8. Capacity or temperature measurement socket. Using this socket
(uncharged!) capacitors and also temperatures (using the avai-
lable optional NiCrNi probe) can be measured.
9. RS-232 interface for the connection of an interface cable for
data transfer to an IBM compatible Windows 95 PC.

5.1Fitting the battery – changing the battery and
testing the fuses
5.1.1 Fitting the battery – changing the battery
In order for your measuring device to function perfectly, it must be
fitted with a 9V dry cell battery. When the battery change symbol
appears in the display the battery must be replaced. To do this,
proceed as follows:
Disconnect the measuring instr ument from the circuit being mea-
sured, remove the test leads from the instrument, switch it off,
remove the holster (if present) and loosen the two captive fixing
screws on the underside of the case with a suitable screwdriver.
Now carefully remove the sockets cover (if necessary with a thin-
bladed screwdriver). In addition note the following diagram. Dis-
connect the used battery from its connecting clip and replace the
battery with a fresh one of the same type. Remember to push the
sheath, if present, onto the battery again.
After successfully replacing the battery place it in the battery com-
partment and carefully close this once more. Take care that the
connecting clips leads do not become crushed.

Attention!
Do not in any event operate the measuring device when it is
open! Danger to life!
Do not leave used batteries in the measuring instrument, becau-
se even leak-proof batteries can corrode and thereby release che-
micals, which are both damaging to health and can destroy the
battery compartment. Used batteries are to be regarded as waste
requiring special handling and so do not belong with general
refuse. Used batteries must be disposed of in an environ-mental-
ly-friendly manner at suitable collection points (specialist trade or
scrap recovery yard).
5.1.2 Fuse testing
Note
Two fuses are built into the measuring instrument, an 800 mA
fuse for the current measurement range up to 400 mA max. and
a 20 A fuse for the current measurement range up to 20 A max.
Both fuses are quick-acting. Changing a fuse is described under
"3. Safety regulations".
