Intended Use - VOLTCRAFT VC281 TRMS Bedienungsanleitung

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 direct and alternating voltages up to 600 V
- Direct measurement of direct and alternating currents up to 600 mA
- Contactless measurement of direct and alternating currents up to 60 A with a CLA60 clamp transformer
- Measures frequency from 10 Hz to 10 MHz (max. 30 Vrms)
- Measures capacitance up to 60 mF
- Measures resistance up to 60 MΩ
- Continuity tests (<10 Ω acoustic)
- Diode tests
The measurement modes are selected using the rotary control. In many measurement ranges, measurement range
selection is automatic (except for continuity testing, diode testing and current measurement ranges).
Effective (True RMS) measurements are displayed when measuring AC voltages/currents with a frequency of up to
400 Hz. This ensures that sinusoidal and non-sinusoidal voltage/currents are measured accurately.
Negative polarity readings are indicated with the (-) sign.
A low-impedance mode (LoZ) enables voltage measurement with reduced internal resistance. This suppresses phan-
tom voltages, which may occur in high-impedance measurements. Measurement with reduced impedance is only
permissible in measurement circuits of up to 250 V and for up to 3 s.
The two current measurement inputs are protected against overload. The voltage in the measurement circuit must
not exceed 600 V.
The current clamp measurement input is equipped with a maintenance-free PTC protection component.
The mA/µA measurement input is equipped with self-resetting PTC fuses. In the case of overload, the current flow is
limited and the measurement device is protected. This negates the need for fuse changes with this measurement mode.
The multimeter is powered by a standard 9 V block battery (type 6F22, NEDA 1604 or identical specifications). The
current clamp requires two standard micro batteries (AA, LR3 or equivalent). The device may only be operated with the
specified batteries. Due to their low capacity and partly lower cell voltage, rechargeable batteries should not be used.
The device switches off automatically after 15 minutes if no buttons are pressed. This prevents the battery from drain-
ing. The automatic shut-off function can be disabled.
There is a fold-out stand on the rear of the device. This allows the multimeter to be positioned for optimum readability.
Do not use the multimeter and current clamp 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 may 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.
