3. Produto acabadoview

The Yato YT-28631 is a compact, pen-style digital voltage tester. It features both contact and inductive testing methods for voltage detection, along with capabilities for testing circuit breaks, diodes, transistors, resistors, and capacitors.

Figure 1: Yato YT-28631 Voltage Tester. The image shows the red and black body of the tester, with the red protective cap removed from the metal testing tip. The Yato logo and model number YT-28631 are visible on the body, along with indicator lights and a pocket clip.

Componentes principais:

• Dica de teste: Used for direct contact measurements.
• Luzes indicadoras: Provide visual feedback during testing (e.g., voltage presence).
• Clip de bolso: Para facilitar o transporte.
• Compartimento da bateria: Located at the rear, for LR44 batteries.

4. Configuração

Instalação da bateria:

The Yato YT-28631 Voltage Tester requires 2x LR44 1.5V batteries for operation. Batteries are not included with the device.

1. Locate the battery compartment cover, typically at the rear end of the tester.
2. Remova a tampa com cuidado.
3. Insert two LR44 1.5V batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
4. Recoloque a tampa do compartimento da bateria com segurança.

5. Instruções de operação

The YT-28631 offers multiple testing functions. Always ensure the area is safe and the circuit is de-energized before performing contact tests, unless specifically testing for live voltage.

5.1. Vol. CAtage Testing (Contact Method)

• Faixa: 70-250V AC
• Touch the metal testing tip of the tester to the live conductor (e.g., inside a wall socket or wire).
• Observe the indicator lights. Illumination indicates the presence of AC voltage dentro do intervalo especificado.

5.2. Vol. CAtage Testing (Inductive Method)

• Faixa: 70-1000V AC
• Hold the tester near an insulated wire or cable.
• The tester will detect the electromagnetic field of live AC voltage without direct contact. Indicator lights will illuminate if voltage é detectado.

5.3. Vol. CCtage Testing (Contact Method)

• Faixa: 1.5-9V DC
• Touch the metal testing tip to the positive terminal of the DC source (e.g., battery).
• Observe the indicator lights. Illumination indicates the presence of DC voltage dentro do intervalo especificado.

5.4. Other Tests (Circuit Breaks, Diode, Transistor, Resistor, Capacitor)

The tester can also be used for basic continuity and component testing. For detailed procedures on these specific tests, refer to standard electrical testing practices and ensure the circuit or component is completely de-energized before testing.

• Circuit Breaks: Use the contact method to trace wires and identify breaks in continuity.
• Teste de Diodo: Can indicate basic functionality (forward/reverse bias).
• Teste de transistor: Can indicate basic functionality (NPN/PNP type).
• Teste de resistor: Can indicate basic continuity.
• Teste de capacitor: Can indicate basic charge/discharge.

6. Manutenção

Limpeza:

Wipe the tester with a dry, clean cloth. Do not use abrasive cleaners or solvents, as these may damage the casing ou componentes internos.

Substituição da bateria:

When the indicator lights become dim or the tester fails to respond, replace the batteries. Follow the battery installation steps in Section 4. Dispose of used batteries responsibly according to local regulations.

Armazenar:

Store the tester in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.

7. Solução De Problemas

• Tester not turning on / No indicator lights:
  • Verifique a instalação e a polaridade da bateria.
  • Replace batteries with new LR44 1.5V cells.
• Inconsistent readings / False positives:
  • Ensure proper contact with the conductor for contact method tests.
  • For inductive tests, ensure no other strong electromagnetic fields are interfering.
  • Verify the tester is clean and free from moisture.
• Tester appears damaged:
  • Discontinue use immediately. Do not attempt repairs.
