6. Instruccions de funcionament
6.1. Encendre/apagar
To turn the device on, rotate the function selector dial to the desired measurement mode. To turn off, rotate the dial to the 'OFF' position.
6.2. Insulation Resistance Measurement (GΩ)
This mode is used to measure the insulation resistance of electrical systems and components.
- Assegureu-vos que el circuit a prova estigui desenergitzat i descarregat de manera segura.
- Rotate the function selector dial to one of the insulation test voltage settings (e.g., 50V, 100V, 250V, 500V, 1000V).
- Connect the test leads to the circuit or component being tested. Typically, the red lead to the live/phase conductor and the black lead to the neutral/earth.
- Manteniu premut el botó PROVA button to initiate the measurement. The test voltags'aplicarà e.
- Read the insulation resistance value displayed on the LCD.
- Allibera el PROVA button to stop the measurement. The circuit will be discharged automatically.
6.3. Índex de polarització (PI) i ràtio d'absorció dielèctrica (DAR)
The ET-200 can calculate PI and DAR, which are indicators of insulation quality.
- To perform a PI or DAR test, select the appropriate insulation test voltage.
- Premeu el botó dedicat PI/DAR button (if available) or follow the on-screen prompts after initiating an insulation test.
- The device will automatically take measurements at specific time intervals (e.g., 30s, 60s, 10min) and calculate the ratios.
6.4. Resistance Measurement (Ω/kΩ)
This mode measures standard resistance values.
- Gireu el selector de funcions fins a la Ω or kΩ posició.
- Ensure the component or circuit is de-energized.
- Connecteu els cables de prova al component que s'ha de mesurar.
- Llegiu el valor de resistència a la pantalla.
6.5. Voltage Measurement (ACV/DCV)
This mode measures AC or DC voltage.
- Gireu el selector de funcions fins a la ACV or DCV posició.
- Connect the test leads in parallel with the circuit or power source to be measured.
- Llegeix el voltage valor a la pantalla.
