Intended Use - VOLTCRAFT VC880 Bedienungsanleitung

2. 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 categories.
- Measurement of direct and alternating voltage up to 1,000 V
- Measurement of direct and alternating current up to 10 A
- Frequency measurement up to 400 MHz
- Capacity measurement up to 40 mF
- Measuring impedance values of up to 40 MΩ
- Continuity test (<20 Ω acoustic)
- Diode test
- Temperature measurement from –40 to + 1000 °C
- Signal ratio display (duty cycle) in %
- 1 kHz low-pass filter alternating voltage measurement
- Comparative value measurement
- Measured value storage and datalogger for 1000 values
- Data transfer per optical interface
The measurement functions are selected using the rotary control. The measuring range is selected automatically for
all measuring functions (except for diode and continuity tests). Manual setting is possible at any time.
The VC880 shows actual effective measured values (True RMS) in the direct and alternating 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 in CAT III or 600 V in CAT IV.
A low-impedance function (low imp) enables measuring with reduced internal impedance. This suppresses phantom
voltages that may appear in high-impedance 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 button, you can hear a signal sound,
and there will be a warning shown in the display.
The multimeter is operated with a common 9V alkaline battery block. The device must only be operated with the spec-
ified battery type. 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 com-
partment cover is missing. The protection device does not permit the battery and fuse covers to be opened when the
measuring lines are inserted into the measuring jacks. Similarly, inserting the measuring lines is prevented when the
battery and fuse covers are open.
Measuring in damp rooms or under unfavourable ambient conditions is not permitted. Unfavourable ambient condi-
tions are: Moisture or high air humidity, dust and flammable gases, fumes or solvents, thunderstorms or thunderstorm
conditions like strong electrostatic fields, etc.
Only use measuring lines or accessories which are adjusted to the specifications of the multimeter when measuring.
