5. Configuración

5.1. Instalación de la batería

The IRT803 requires four (4) AA batteries for operation. To install or replace batteries:

1. Asegúrese de que el comprobador esté apagado.
2. Localice el compartimiento de la batería en la parte trasera de la unidad.
3. Utilice un destornillador para abrir la tapa del compartimento de la batería.
4. Insert the four AA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
5. Cierre bien la tapa del compartimento de la batería.

5.2. Conexión de los cables de prueba

Connect the test leads to the appropriate input jacks on the tester. For most measurements, the red lead connects to the 'V Ω INSULATION' jack and the black lead connects to the 'COM' (common) jack. Ensure connections are firm and secure.

6. Instrucciones de funcionamiento

6.1. Powering On/Off and Display Backlight

• To power on the unit, rotate the selector dial from 'OFF' to any desired measurement function.
• To power off, rotate the selector dial back to 'OFF'. The unit also features auto power-off to save battery life after a period of inactivity.
• Presione el SELECCIONAR button (often indicated by a light bulb icon) to toggle the display backlight on or off.

6.2. Prueba de resistencia de aislamiento

The IRT803 can perform insulation resistance tests at various voltages.

1. Seleccionar volumen de pruebatage: Rotate the selector dial to the desired insulation test voltage (50 V, 100 V, 250 V, 500 V o 1000 V).
2. Conectar los cables de prueba: Connect the red test lead to the circuit under test and the black test lead to the ground or common point. Ensure the circuit is de-energized.
3. Iniciar prueba: Press and hold the large red PRUEBA button to begin the insulation test. The test voltage will be applied, and the resistance reading will be displayed.
4. Función de bloqueo: For continuous testing, press the CERRAR button after initiating the test. This will maintain the test voltage without needing to hold the PRUEBA botón. prensa PRUEBA de nuevo para desbloquear.
5. Compare Function: Utilice el COMPARAR button to set a reference value and compare subsequent readings against it.
6. Prueba PI/DAR: Select the PI/DAR function on the dial. The meter will automatically perform the Polarization Index and Dielectric Absorption Ratio tests, displaying the calculated values.
7. Read and Record: Observe the reading on the LCD. Use the SOSTENER button to freeze the display for easier recording.
8. Descargar: After completing an insulation test, the circuit under test should be discharged. The IRT803 typically handles this automatically, but always exercise caution.
