2. INTENDED USE
• Measuring and displaying electric parameters in the range of overvoltage category CAT IV up to
max. 600 V 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 voltage up to max. 1000 V
• Measurement of direct and alternating currents up to max. 10 A
• Frequency measuring up to 60 MHz
• Measurement of capacities up to 60 mF
• Measurement of resistances up to 60 MΩ
• Continuity test (<10 Ω acoustic)
• Diode test
• Measurement of temperature from -40 to +1000 ºC
• Display of duty cycle in % (10 – 90 %)
• 1 kHz low pass filter alternating voltage measurement
• Comparison value measurement
• Data memory and data logger for 1000 values with time stamp
• Data transmission to a PC via optical interface
• Date and time display
The measuring functions are selected using the rotary switch. The measuring range selection is
automatic for all measuring functions (except for diode and continuity test). Manual setting is possible
at any time.
The VC890 SE displays true RMS in both the direct and alternating voltage and current range.
For negative values, the polarity will automatically be displayed with the sign (-).
The two current measuring inputs are secured against overload with ceramic high-performance fuses.
The voltage in the current measuring circuit may not exceed 1000 V in CAT lll or 600 V in CAT IV.
A low impedance (Low Imp) function allows measurement with reduced internal resistance. This
suppresses phantom voltages which could appear in high-resistance measurements. Measurement
with reduced impedance is only permitted in measuring circuits up to max. 1000 V and only for max.
3 s. When the Low Imp button is pressed, a signal will sound and a warning indicator will be displayed.
The multimeter is powered by a standard 9 V alkaline or lithium monobloc battery. Operation is only
permitted with the specified battery type. An automatic power off prevents the battery from draining
prematurely if the device is not used for a period of time (settings: 5 min., 15 min., 30 min. or OFF;
see Chapter "19. Auto Power Off function"). The Auto Power Off function is switched off during data
transmission to a PC via optical interface.
