4. Setélan

4.1. Pamasangan batré

The Metrel MD9231 is powered by two 1.5 V AAA batteries. To install or replace batteries:

1. Ensure the meter is turned OFF and disconnect any test leads from the input terminals.
2. Panggihan panutup kompartemen batré di tukang méteran.
3. Anggo obeng pikeun ngaleupaskeun sekrup anu ngamankeun panutupna.
4. Remove the cover and insert two new 1.5 V AAA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
5. Pasang deui panutup kompartemen batré teras kencengkeun sekrupna pageuh.

Always use fresh batteries of the specified type. Dispose of old batteries responsibly according to local regulations.

5. Parentah Operasi

5.1. Daya Hurung / Pareum

To turn the meter ON, rotate the function switch from the 'OFF' position to any desired measurement function. To turn the meter OFF, rotate the function switch back to the 'OFF' position. The meter features an auto power-off function to conserve battery life, which will activate after a period of inactivity.

5.2. Pamilihan fungsi

Use the rotary switch to select the desired measurement function. The available functions include:

• AC / DC Voltage (V): Pikeun ngukur voltage nepi ka 1000 V.
• AC/DC Current (A): For measuring current up to 1000 A using the clamp rahang.
• Résistansi (Ω): For measuring resistance.
• Kontinuitas ()))): For checking circuit continuity with an audible indicator.
• Uji dioda (▶|): Pikeun nguji dioda.
• Capacitance (µF): For measuring capacitance.
• Frékuénsi (Hz): For measuring frequency.
• VFD (Variable Frequency Drive): For accurate measurements in VFD environments.
• NCV (Non-Kontak Voltage): For detecting live conductors without physical contact.

5.3. Making Measurements

For Current Measurement (AC/DC A):

1. Rotate the function switch to the AC A or DC A position.
2. Buka clamp jaw by pressing the lever.
3. Encircle only one conductor with the clamp rahang. Pastikeun rahangna katutup sapinuhna.
4. Baca nilai ayeuna dina tampilan LCD.

Pikeun Voltage, Resistance, Capacitance, Diode, and Frequency Measurements:

1. Rotate the function switch to the desired V, Ω, µF, or Hz position.
2. Insert the black test lead into the 'COM' terminal and the red test lead into the 'VΩHz' terminal.
3. Connect the test probes to the circuit or component under test.
4. Maca ukuran dina tampilan LCD.

5.4. Fungsi Husus

• Tombol PILIH: Toggles between AC/DC modes or different sub-functions within a rotary switch position (e.g., VFD, NCV).
