2. Informações de segurança

Always observe basic safety precautions when using electrical testing equipment to reduce the risk of fire, electric shock, or personal injury. Improper use can result in electric shock or damage to the meter.

• Não aplicar voltage excedendo a tensão nominal máximatage between the terminals or between any terminal and earth ground.
• Tenha cuidado ao trabalhar com voltagacima de 30V AC RMS, 42V pico ou 60V DC. Essas tensõestagrepresentam um risco de choque.
• Always ensure the test leads are in good condition and properly connected before making measurements.
• Não utilize o medidor se ele parecer danificado ou se o circuito estiver aberto.asing está aberto.
• Remova os cabos de teste do circuito antes de alterar as funções.
• Substitua as pilhas quando o indicador de bateria fraca acender para garantir leituras precisas.

4. Configuração

4.1 Instalação da bateria

The ANENG DT3266L requires two AAA 1.5V batteries for operation. Ensure correct polarity when installing.

1. Localize a tampa do compartimento da bateria na parte traseira do multímetro.
2. Use uma chave de fenda para remover o parafuso que prende a tampa da bateria.
3. Insert two AAA 1.5V batteries, observing the polarity markings (+ and -) inside the compartment.
4. Recoloque a tampa da bateria e prenda-a com o parafuso.

5. Instruções de operação

To operate the multimeter, turn the rotary switch to the desired measurement function. Connect the test leads or use the clamp jaw as appropriate for the measurement type.

5.1 Medição de corrente alternada

Para medir a corrente alternada, use o clamp mandíbula. Certifique-se de que o circuito esteja desenergizado antes de fecharamping, if possible, or exercise extreme caution.

1. Turn the rotary switch to the '20A' or '200A' AC current range.
2. Abra o clamp mandíbula pressionando o gatilho.
3. Enclose only one conductor (e.g., the Live wire) within the clamp mandíbula. Não fecheamp around both Live and Neutral wires simultaneously, as this will result in an inaccurate zero reading.
4. Feche a clamp mandíbula firmemente.
5. Leia o valor da corrente alternada no visor LCD.

5.2 Vol AC/DCtage Medição

Para medir o vol AC ou DCtage, use the provided test leads.

1. Insert the black test lead into the 'COM' jack and the red test lead into the 'VΩ' jack.
2. Turn the rotary switch to the desired ACV (e.g., '600V~') or DCV (e.g., '600V-') range.
3. Conecte as pontas de prova ao circuito ou componente a ser medido.
4. Leia o vol.tage valor no display LCD.

5.3 Medição de Resistência

To measure resistance, ensure the circuit is de-energized before connecting the test leads.

1. Insert the black test lead into the 'COM' jack and the red test lead into the 'VΩ' jack.
2. Turn the rotary switch to the desired resistance range (e.g., '2KΩ', '200KΩ', '2MΩ').
3. Conecte as pontas de prova nos terminais do componente cuja resistência se deseja medir.
4. Leia o valor da resistência no visor LCD.

5.4 Live Wire Identification (L LIVE)

This function helps identify live wires. Refer to the product overview for the specific 'L (LIVE)' setting on the rotary switch.

1. Turn the rotary switch to the 'L (LIVE)' position.
2. Carefully touch the red test probe to the conductor suspected of being live.
3. The meter will indicate if the wire is live, typically through an audible beep or a specific display icon.

5.5 Função HOLD

Press the 'HOLD' button to freeze the current reading on the LCD display. Press it again to release the hold and resume live readings.

5.6 LIGHT Function

Press the 'LIGHT' button to activate the backlight for the LCD display, improving visibility in dimly lit environments. Press it again to turn off the backlight.

6. Measurement Techniques

6.1 Correct AC Current Measurement

For accurate AC current measurement using the clamp function, ensure that only a single conductor (e.g., the Live wire) passes through the clamp jaw. Clamping around multiple conductors carrying current in opposite directions will result in an incorrect reading, often zero.

Figura 6.1: Correct method for AC current measurement: Clamp around a single conductor (Live wire).

6.2 Incorrect AC Current Measurement

Nunca clamp the multimeter around both the Live (L) and Neutral (N) wires simultaneously when measuring AC current. The magnetic fields will cancel each other out, leading to an inaccurate or zero reading.

Figura 6.2: Incorrect method for AC current measurement: Do not clamp around both Live (L) and Neutral (N) wires together.

7. Manutenção

7.1 Limpeza

Limpe o medidor casing com anúncioamp Limpe com pano e detergente neutro. Não utilize abrasivos ou solventes. Certifique-se de que o medidor esteja completamente seco antes de usar.

7.2 Substituição da bateria

When the low battery indicator appears on the display, replace the batteries as described in Section 4.1 to ensure continued accurate operation.

7.3 Armazenamento

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

8. Solução De Problemas

Se o multímetro não estiver funcionando como esperado, considere os seguintes problemas comuns:

• Sem imagem ou imagem muito fraca: Verifique a instalação e a carga da bateria. Substitua as baterias, se necessário.
• Leituras incorretas: Ensure the correct function is selected on the rotary switch. Verify test lead connections. For current measurements, ensure only a single conductor is within the clamp mandíbula.
• No response: Ensure the meter is turned ON. Check for any visible damage to the meter or test leads.

If problems persist, discontinue use and consult a qualified technician.
