Intended Use
- Measuring and displaying electric parameters in the range of overvoltage CAT IV (up to max. 600V or
CAT III up to max.1000 V against ground potential, pursuant to EN 61010-1) and all lower categories.
- Measurement of direct and alternating voltages up to a maximum of 1,000 V/DC/, 750 V/AC
- Measurement of direct and alternating current up to 10 A
- Frequency measurement up to 10 MHz
- Capacity measuring up to 4000 µF
- Measuring resistance values of up to 60 MΩ
- Continuity check (< 30 Ω acoustic)
- Diode test
- Temperature measuring from –40 to + 1,000 °C (only VC850)
The measurement functions are selected using the rotary switch. The measuring range is selected auto-
matically for all measuringfunctions (except for diode and continuity tests). Manual setting is possible at
any time.
The VC850 shows actual effective measured values (True RMS) in the voltage and current measuring
area. For VC830, the average value (RMS Sinus) is displayed. Polarity is displayed automatically.
The two current measuring inputs are secured against overload. The voltage in the current measuring
circuit must not exceed 1,000 V category III or 600 V in category IV. The two current measuring ranges
are protected by ceramic high-performance fuses.
Alow-impedance function (low imp) enables measuring with reduced internal resistance. This suppres-
ses phantom voltages that may appear in high-ohm measurements. Measuring with reduced impedance
is only permitted for measuring circuits of up to 1,000 V and for up to 3 s. When pressing the low imp but-
ton, you can hear a signal sound, and there will be a warning shown in the display.
The multimeter is operated with a common 9 V alkaline battery block. The device may only be operated
with the specified batteries.
The multimeter must not be operated when it is open, i.e. with an open battery compartment or when the
battery compartment cover is missing. The protection device does not permit the battery and fuse lids to
be opened when the measuring lines are inserted into the measuring jacks. Similarly, inserting the mea-
suring lines is prevented when the battery and fuse lids are open.
Measuring in damp rooms or under unfavourable ambient conditions is not permitted. Unfavourable
ambient conditions are:
- Wetness or high air humidity
- Dust and flammable gases, vapours or solvent,
- Thunderstorms or similar conditions such as strong electrostatic fields etc.
For safety reasons, only use measuring cables or accessories which are adjusted to the specifications of
the multimeter when measuring.
Any use other than the one described above damages the product. Moreover, this involves dangers such
as e.g. short circuit, fire, electric shock, etc. No part of the product must be modified or rebuilt!
Read the operating instructions carefully and retain them for later reference.
The safety instructions must be observed at all times.
