Intended Use - VOLTCRAFT VC870 Bedienungsanleitung

Intended Use

- Measuring and displaying electric parameters in the range of overvoltage CAT IV for up to max. 600V
or CAT III for up to max.1000 V against ground potential, pursuant to EN 61010-1 and all lower cate-
gories.
- 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 400 MHz
- Capacity measurement up to 40 mF
- Measuring resistance values of up to 40 MΩ
- Continuity check (< 20 Ω acoustic)
- Diode test
- Temperature measuring from –40 to + 400 °C
- DC loop current measuring from 0 – 100 % (for signal currents of 4 – 20 mA)
- AC output measuring up to max. 2500 W through included adapter
The measurement functions are selected using the dial switch. The measuring range is selected auto-
matically for all measuring functions (except for diode and continuity tests). Manual setting is possible at
any time.
The VC870 shows actual effective measured values (True RMS) in the voltage and current measuring
area. Polarity is automatically indicated with the prefix (-) in case of negative measured values.
The two current measuring inputs are secured against overload with ceramic high-performance fuses. The
voltage in the current measuring circuit must not exceed 1,000 V category III or 600 V in category IV.
A low-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. Automatic switching off prevents premature emptying of the battery if the
device is not used for approx. 15 minutes. When the interface is active, this function is switched off.
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: Moisture or high air humidity, dust and flammable gases, fumes or solvents,
thunderstorms or thunderstorm conditions like 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.
