VOLTCRAFT VC-522 AC Mode D'emploi page 33

3. Intended use
• Measures and displays electrical parameters in measurement category CAT III (up to 600 V). Complies with the EN
61010-1 standard and all lower categories. The multimeter must not be used in the measuring category CAT IV.
• Measures alternating current up to max. 400 A (AC-TrueRMS)
• Measures direct current up to max. 400 A (VC-523/VC-523 SE only)
• Measures DC and AC voltages up to 600 V (AC-TrueRMS)
• Measures frequency up to 10 kHz
• Measures temperature from -20 to +760 °C
• M easures resistance up to 40 MΩ
• Measures capacity up to 1000 µF
• C ontinuity test (<50 Ω acoustic)
• Diode test
• N on-contact alternating voltage measurement (NCV) ≥230 V/AC and ≤50 mm gap
The measurement modes are selected using the rotary dial. The measuring range is selected automatically in many
measurement modes and can also be set manually.
Effective (True RMS) measurements are displayed when measuring AC voltages/currents.
Negative polarity readings are indicated with the (-) sign.
The current is measured via the current clamp. The circuit does not need to be opened to take a measurement. The
current clamp can also be used to take measurements on uninsulated, hazardous conductors. The voltage in the
measuring circuit must not exceed 600 V in CAT III. The use of personal protective equipment is recommended for
CAT III measurements.
The multimeter is powered by three 1.5 V AAA batteries. Only use batteries of the specified type. Do not use 1.2 V re-
chargeable batteries. The multimeter switches off automatically to prevent the batteries from draining. The automatic
power-off feature can be disabled.
Do not use the multimeter when the battery compartment is open or when the battery compartment cover is missing.
Do not take measurements in potentially explosive areas, damp rooms or adverse conditions. Adverse conditions
include: Moisture or high humidity, dust and flammable gases, vapours or solvents, thunderstorms, and strong elec-
tromagnetic fields.
For safety reasons, only use test leads or accessories that match the multimeter's specifications.
The multimeter must only be used by people who are familiar with the relevant regulations and understand the poten-
tial hazards. The use of personal protective equipment is recommended.
This product is not intended to be used by people (including children) with impaired physical, sensory or mental
capabilities or lack of experience and/or lack of knowledge. The use of measuring devices must be supervised by
trained personnel.
