VOLTCRAFT VC131 Handheld Multimeter User Manual

1. Einleitung

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. Einrichtung

4.1 Einlegen der Batterie

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

1. Ensure the multimeter is turned OFF and disconnect all test leads from the device and any circuits.
2. Suchen Sie das Batteriefach auf der Rückseite des Multimeters.
3. Using a screwdriver, loosen the screw securing the battery compartment cover.
4. Nehmen Sie die Abdeckung ab.
5. Legen Sie die 9V-Batterie unter Beachtung der richtigen Polarität (+ und -) ein.
6. Bringen Sie die Abdeckung des Batteriefachs wieder an und ziehen Sie die Schraube fest.

4.2 Anschließen der Testleitungen

Für genaue und sichere Messungen ist der korrekte Anschluss der Messleitungen unerlässlich.

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. Für die meisten Bändetage, 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. Stellen Sie sicher, dass die Messleitungen vollständig eingeführt und fest angeschlossen sind.
5. If necessary, remove the protective caps from the test lead tips for specific measurement points.

5. Bedienungsanleitung

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

5.1 Ein-/Ausschalten

• 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 Messfunktionen

Select the desired function using the central rotary switch.

• DC-Voltage (V–): For measuring direct current voltage. Schließen Sie die Leitungen parallel an den Stromkreis an.
• AC-Lautstärketage (V~): For measuring alternating current voltage. Schließen Sie die Leitungen parallel an den Stromkreis an.
• Widerstand (Ω): For measuring electrical resistance. Ensure the circuit is de-energized before measuring.
• Kontinuität (•))): For checking circuit continuity. An audible beep indicates continuity.
• Diode Test (•|•): Zum Testen von Dioden.
• 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 Sonderfunktionen

• Halte den Knopf: Drücken Sie, um den aktuellen Messwert auf dem Display einzufrieren. Drücken Sie erneut, um die Anzeige freizugeben.
• Taschenlampenfunktion: 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.
• Kontaktloses Volumentage (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 ohne direkten Kontakt.

6. Wartung

6.1 Reinigung

Um die Leistungsfähigkeit und das Aussehen des Geräts zu erhalten:

• Wischen Sie das casing mit Adamp Ein Tuch und ein mildes Reinigungsmittel verwenden. Keine Scheuermittel oder Lösungsmittel verwenden.
• Achten Sie darauf, dass keine Feuchtigkeit in das Gerät eindringt.

6.2 Batteriewechsel

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

6.3 Sicherungswechsel

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

• Stellen Sie sicher, dass das Multimeter ausgeschaltet und alle Messleitungen abgeklemmt sind.
• Öffnen Sie die Rückseite 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.
• Schließen Sie die c sicher.asing.
