VOLTCRAFT VC131 Handheld Multimeter User Manual

1. Introduktion

The VOLTCRAFT VC131 is a robust and versatile handheld digital multimeter designed for a wide range of electrical measurement tasks. It serves as an excellent entry-level device, replacing previous models like the VC-130 and VC-135. This multimeter features an automatic measuring range selection function, making it user-friendly for both alternating (AC) and direct (DC) current measurements, though current measurement is limited to DC. Its razor-sharp EBTN display ensures clear readability in various lighting conditions, with a 2.2-inch diagonal screen for large, easy-to-read numbers and symbols. The device is built with a durable two-component housing, integrated soft rubber protection, and slightly raised edges to safeguard the display, rotary switch, and buttons, ensuring longevity and a secure grip even in demanding environments.

Key features include tilt protection for stability, a non-slip design, a built-in torch function for illuminating dark work areas, and a non-contact voltage (NCV) sensor for safely detecting live cables without direct contact. The measuring tips are equipped with removable protective caps for enhanced safety and versatility.

4. Opsætning

4.1 Batteriinstallation

The VOLTCRAFT VC131 requires a 9V (1604, 6F22) battery for operation. To install or replace the battery:

1. Sørg for, at multimeteret er slukket, og frakobl alle testledninger fra enheden og eventuelle kredsløb.
2. Find batterirummet på bagsiden af ​​multimeteret.
3. Using a screwdriver, loosen the screw securing the battery compartment cover.
4. Fjern dækslet.
5. Insert the 9V battery, observing the correct polarity (+ and -).
6. Sæt dækslet til batterirummet på igen, og spænd skruen godt fast.

4.2 Tilslutning af testledninger

Korrekt tilslutning af testledninger er afgørende for nøjagtige og sikre målinger.

Figure 4.1: The VC131 Multimeter shown with its included red and black test leads, ready for connection.

1. Insert the black test lead into the "COM" (common) jack. This is the negative (-) input.
2. For de fleste volumenertage, resistance, continuity, and diode measurements, insert the red test lead into the "VΩmA" jack. This is the positive (+) input.
3. For high DC current measurements (up to 10A), insert the red test lead into the "10A max" jack.
4. Ensure the test leads are fully inserted and securely connected.
5. If necessary, remove the protective caps from the test lead tips for specific measurement points.

5. Betjeningsvejledning

The VC131 features a rotary switch for selecting measurement functions and buttons for additional features.

5.1 Tænd/sluk

• To turn on the multimeter, rotate the function switch from "OFF" to any desired measurement function.
• To turn off the multimeter, rotate the function switch to the "OFF" position.

5.2 Målefunktioner

Select the desired function using the central rotary switch.

• DC bindtage (V–): For measuring direct current voltage. Connect leads in parallel to the circuit.
• AC Voltage (V~): For measuring alternating current voltage. Connect leads in parallel to the circuit.
• Modstand (Ω): For measuring electrical resistance. Ensure the circuit is de-energized before measuring.
• Continuity (•))): For checking circuit continuity. An audible beep indicates continuity.
• Diode Test (•|•): Til test af dioder.
• DC Current (A–, mA–, µA–): For measuring direct current. Connect leads in series with the circuit. Note: AC current measurement is not supported by this model.

5.3 Specialfunktioner

• HOLD knap: Tryk for at fryse den aktuelle aflæsning på displayet. Tryk igen for at slippe.
• Lommelygtefunktion: The built-in LED light can be activated to illuminate the work area. Refer to the device for the specific button or switch to activate the torch.
• Non-Contact Voltage (NCV):

  To use the NCV function, rotate the switch to the NCV position. Place the front of the multimeter near the suspected live wire. The NCV sensor will detect the electromagnetic field, providing an audible and/or visual indication of voltage presence. This is useful for locating live cables through insulation or checking for voltage uden direkte kontakt.

6. Vedligeholdelse

6.1 Rengøring

For at bevare enhedens ydeevne og udseende:

• Tør casing med annonceamp klud og et mildt rengøringsmiddel. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
• Sørg for, at der ikke kommer fugt ind i enheden.

6.2 Udskiftning af batteri

Replace the 9V battery when the low battery indicator appears on the display. Refer to Section 4.1 for detailed instructions.

6.3 Udskiftning af sikringer

If the current measurement function stops working, the fuse may need replacement. This procedure should only be performed by qualified personnel.

• Sørg for, at multimeteret er slukket, og at alle testledninger er frakoblet.
• Åbn bagsiden casing of the multimeter (this may require removing more screws than just the battery cover).
• Locate the fuse(s).
• Replace the blown fuse with a fuse of the exact same type and rating (e.g., 10A max FUSED, 200mA max FUSED). Refer to the markings near the input jacks for fuse specifications.
• Luk c'en sikkertasing.
