  • VΩHz%mA Jack: Para o cabo de teste vermelho ao medir o volumetage, resistance, frequency, capacitance, or current (up to 200mA).

5. Configuração

5.1 Instalação da bateria

The DMMW3 uses one CR2032 coin cell battery. If the low battery indicator appears on the display, or if the unit does not power on, replace the battery:

1. Certifique-se de que o multímetro esteja desligado e desconecte todos os cabos de teste.
2. Localize o compartimento da bateria na parte traseira da unidade.
3. Utilize uma pequena chave de fenda para abrir a tampa do compartimento da bateria.
4. Remove the old CR2032 battery, noting its polarity.
5. Insira uma nova bateria CR2032 com o lado positivo (+) voltado para cima.
6. Recoloque a tampa do compartimento da bateria e prenda-a com o parafuso.

5.2 Conectando os Cabos de Teste

Always connect the test leads correctly for accurate and safe measurements:

• Insira a ponta de prova preta no COM Conector de entrada (comum).
• Insira o cabo de teste vermelho no VΩHz%mA input jack for most measurements (voltage, resistance, continuity, diode, capacitance, frequency, current up to 200mA).

6. Instruções de operação

6.1 Ligar/Desligar

To power on the multimeter, rotate the Function Selector Dial from the OFF position to any desired measurement function. To power off, rotate the dial back to the OFF position (indicated by the power symbol ⏻).

6.2 Seleção de Função

Rotate the Function Selector Dial to choose the primary measurement category:

• mA: For measuring DC or AC current (up to 200mA).
• Ω / Continuity / Diode / Capacitance: For measuring resistance, checking continuity, testing diodes, or measuring capacitance. Use the MODO button to cycle through these functions.
• V: For measuring DC or AC voltage. Use o MODO button to switch between DC and AC voltage.
• Hz%: For measuring frequency or duty cycle. Use the MODO button to switch between frequency (Hz) and duty cycle (%).

6.3 Using Control Buttons

• MODO: Press to select secondary functions within a dial position (e.g., AC/DC, Resistance/Continuity/Diode/Capacitance, Hz/%).
• ALCANCE: Press to switch between auto-ranging and manual ranging. In manual ranging, press repeatedly to cycle through available ranges.
• ESPERA: Pressione para congelar a leitura atual no visor. Pressione novamente para liberar.
• MÁX.: Press to capture and display the maximum value measured during a session. Press again to exit MAX mode.

6.4 Performing Measurements (Exampa)

Always ensure the circuit is de-energized before connecting test leads for resistance, continuity, diode, or capacitance measurements.

6.4.1 DC / AC Voltage Medição

1. Set the Function Selector Dial to V.
2. Pressione o MODO button to select DC or AC voltage (DC or AC indicator on display).
3. Connect the red test lead to the positive (+) side of the circuit and the black test lead to the negative (-) side or ground.
4. Leia o vol.tage valor no display.

6.4.2 Medição de Resistência

1. Certifique-se de que o circuito esteja desenergizado.
2. Set the Function Selector Dial to Ω. Imprensa MODO until the Ω symbol is displayed.
3. Conecte os cabos de teste ao componente que será medido.
4. Leia o valor da resistência no display.

6.4.3 Teste de Continuidade

1. Certifique-se de que o circuito esteja desenergizado.
2. Set the Function Selector Dial to Ω. Imprensa MODO até o símbolo de continuidade (⧸) é exibido.
3. Conecte os cabos de teste ao circuito ou componente.
4. A continuous beep indicates continuity (low resistance). The display will show the resistance value.

7. Manutenção

7.1 Limpeza

Limpe a caixa com anúncioamp Limpe com pano e detergente neutro. Não utilize abrasivos ou solventes. Mantenha os terminais de entrada livres de sujeira e umidade.

7.2 Substituição da bateria

Refer to Section 5.1 for detailed battery replacement instructions. Always use a fresh CR2032 battery.

7.3 Substituição de fusíveis

The DMMW3 has a 200mA MAX FUSED input for current measurements. If the current measurement function stops working, the fuse may need replacement. This procedure should only be performed by qualified personnel.

1. Certifique-se de que o multímetro esteja desligado e desconecte todos os cabos de teste.
2. Open the back casing of the multimeter (this may require removing multiple screws).
3. Locate the fuse.
4. Replace the blown fuse with a fuse of the exact same type and rating (e.g., 200mA, fast-acting).
5. Carefully reassemble the multimeter, ensuring all screws are tightened.

WARNING: Using an incorrect fuse type or rating can damage the meter and pose a serious safety hazard.

7.4 Armazenamento

If the meter is not to be used for an extended period, remove the battery to prevent leakage. Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.
