Safety Rules - Conrad Electronic VC-200 Green DMM Mode D'emploi

1. Introduction
The VC-200 G is equipped with a special feature which is ecologically
beneficial. A so called High Cap is used for power supply in this
multimeter instead of batteries or accumulators.
A High Cap is a capacitor with a very high capacity, but a low nominal
voltage. The power-saving measuring circuit and the power-saving
LC-display can be operated up to two hours and 30 minutes with the
energy it receives from the High Cap. This means there is energy to
make measurements for max. two hours and 30 minutes.
But first of all the High Cap has to be charged. This happens over an
ordinary mains socket and the measuring cables. The measuring unit
has a built-in "power supply" which transforms the 230 V Alternating
Current into the necessary Direct Current which charges the High
Cap. It is also possible to charge the High Cap directly with Direct
Current, e.g. a car battery with 12 VDC. Additionally a solar cell is built
in which transforms the daylight in energy for float loading.
The DMM is switched on or off with a button (green, below the
display). The DMM can be used for hobby and also for industry (with
restrictions, because of IEC 664) and schools and etc.
This product has been tested according to the following EC-
Directives:
• 89/336/EEC (EMC of Nov., 1992, Electromagnetic
Compatibility)
• 73/23/EEC (Product Safty Law of June 11, 1979, Low Voltage
directive of February 19, 1973).

2. Safety Rules

• This unit is constructed and checked according to DIN 57 411
Part 1/VDE 0411 Part 1, protective measures for electrical
measuring units.
This unit left the factory in safe and perfect condition.
To maintain this condition and to guarantee a safe operation the
user has to pay attention by all means to the safety rules and
warnings which are contained in this manual.
• This multimeter may only be used in fuse lines which are protected
with 16 A and which have a maximal load of 4000 VA.
It is not allowed to use the unit for installations in the overload
range III according to IEC 664.
The unit and the measuring cables are not protected against
arcing and are not intended for high energy industrial use.
(IEC 1010-2-031, section 13.101.).
• Keep children away from measuring units!
• Pay attention to the rules for prevention of accidents in industrial
enterprises prescibed by the Industrial Trade Associations for
electrical installations and production facilities.
• When using the unit in schools and hobby-workshops the usage
and the measurement has to be controlled by the responsible
teachers or skilled personell.
• If covers are opened or parts are removed, exept it is possible
without tools, voltage-carrying components can lay open.
Terminals can also carry voltage. If it is necessary to open the unit
before adjustment, maintenance, repairing or exchange of parts
or modules, the measuring unit has to be separated from all
voltage sources and measuring circuits. Repairs or maintenance
to the measuring unit must only be carried out by qualified
service personell or qualified electricians who know the dangers
and the respective rules (VDE 0100, 0701, VDE-0683).
