Intended Use - VOLTCRAFT VC891 Bedienungsanleitung

3 Intended use

– Measures and displays electrical parameters in the measurement category
CAT III (up to 1000 V) or CAT IV (up to 600 V) against earth potential. Com-
plies with the EN 61010-1 standard and all lower categories.
– Measures direct voltage up to 1000 V
– Measures alternating voltage up to 1000 V
– Measures AC+DC mixed voltage up to 1000 V
– Measures direct and alternating currents up to 10 A
– Measures frequency from 10 Hz to 60 MHz (max. 20 Vrms)
– Displays pulse ratio (duty cycle) in %
– Measures capacitance up to 60 mF
– Measures resistance up to 60 MΩ
– Measuring temperatures from -40 to +1000 °C
– Continuity test (Resistance threshold can be set as 1~1000 Ω)
– Diode test
– Bluetooth™ interface for app control
The measurement modes are selected using the control dial. The measurement
range is selected automatically in most modes (except continuity test, diode test and
current measurement ranges).
AC voltage frequency 100kHz
AC current frequency 10kHz
Negative polarity readings are indicated with the (-) sign automatically.
A low-impedance mode (LoZ) enables voltage measurement with reduced internal
resistance. This suppresses phantom voltages, which may occur in high-impedance
measurements. The low-impedance mode must only be used to measure circuits of
up to 1000 V for a maximum of 3 seconds.
The two current measurement inputs are protected against overload with high-
performance ceramic fuses. The voltage in the measuring circuit must not exceed
1000 V.
