Functional description
Apart from the usual measuring functions such as the measure-
ment of current, voltage and resistance, this multimeter enables
you to check transistors and to carry out diode tests. Moreover, it
enables you to carry out continuity tests with acoustic indication.
Furthermore, the device VC
-160
has a so-called AUTO-POWER-
OFF function which means that the device turns itself automatically
off after approx. 15 minutes in order to save energy. The change-
over of the different measuring ranges ="Auto-Range" = automatic
change-over of the range takes place in the functions direct and al-
ternating.
Using the multimeter
a) Inserting and changing the battery
So that the measuring instrument functions perfectly, it must be fit-
ted with two 1.5V AAA batteries. When the change-battery symbol
appears in the display, the batteries must be changed. Proceed as
follows:
- disconnect the measuring instrument from the test circuit,
- remove the test leads from the measuring instrument,
- switch it off and
- unscrew the fastening screws at the back (bottom) of the
housing with an suitable screwdriver (for recessed-head screws).
- now remove the lower shell of the housing (locked at the top)
carefully.
- remove the used batteries from the battery compartment and
- replace with fresh batteries of the same type.
- now close the measuring instrument carefully.
