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.
- Measures direct and alternating voltages up to 600 V
- Measures direct and alternating currents up to 10 A
- Measures resistances up to 20 MΩ
- Battery tests for 1.5 V and 9 V batteries
- Continuity tests (<10 Ω acoustic)
- Diode tests
The measurement modes can be selected using the control dial. The measurement range must be selected manually
on the VC251.
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.
The multimeter features a low-impedance function (LoZ) that enables you to measure the voltage with reduced in-
ternal resistance. This suppresses phantom voltages that may appear in high-impedance measurements. The low-
impedance function must only be used to measure circuits of up to 250 V for a maximum of 3 seconds.
The two current measurement inputs are protected against overload. The voltage in the measuring circuit must not
exceed 600 V.
The 10 A current measuring input is equipped with a ceramic high-performance fuse.
The mA/µA measuring input is equipped with resettable PTC fuses. In the event of an overload, the fuses restrict the
flow of current to protect the multimeter. You do not need to replace the fuses.
The multimeter is powered by a standard 9 V block battery (type 6F22, NEDA 1604 or identical specifications). Only
use batteries of the specified type. Rechargeable batteries have a lower capacity and should not be used.
The device switches off automatically after 15 minutes if no buttons are pressed to prevent the battery from draining.
The automatic power-off function can be disabled.
A fold-out stand is attached to the back of the multimeter. This allows you to place the multimeter on a level surface
for better readability.
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.
Using this product for any purposes other than those described above may damage the product and result in a short
circuit, fire or electric shock. The product must not be modified or reassembled!
Read the operating instructions carefully and keep them in a safe place for future reference.
Always observe the safety information in these instructions.
