2. INTENDED USE
• Measuring and displaying electric parameters in the range of overvoltage CAT II for up to max. 600 V
against ground potential, pursuant to EN 61010-1 and all lower categories.
• Measurement of direct and alternating voltage up to 600 V
• Measurement of direct and alternating current up to 10 A
• Frequency measurement up to 400 MHz
• Capacity measurement up to 4 mF
• Measuring impedance values of up to 40 M

• Continuity test (<10

acoustic)
• Diode test
• Temperature measurement from -40 to +400 ºC
• Signal ratio display (duty cycle) in %
• 1 kHz low-pass
fi
lter alternating voltage measurement
• Comparative value measurement
• Measured value storage and datalogger for 1000 values
• Data transfer per USB 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 VC650BT shows actual effective measured values (True RMS) in the direct and alternating
voltage and current measuring area.
Polarity is automatically indicated with the pre
fi
x (-) 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 600 V in CAT II.
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 600 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 six 1.5 V batteries type C or 230 V/AC, 50 Hz. Automatic switching off
saves power if the device is not used for approx. 15 minutes. (The function is activated only when the
multimeter is powered by batteries). 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
covers to be opened when the measuring leads are inserted into the measuring jacks.
