2. Connexió dels cables de prova: Connect the appropriate test leads to the input terminals on the DT-6650. Ensure a firm connection for accurate readings and safety. For specific tests like earth resistance, use the provided ground stakes and leads as shown in Figure 4.

   

3. Encès: Turn the rotary dial to the desired measurement function to power on the device. The 3.5-inch TFT color LCD display will illuminate.

Funcionament

The DT-6650 features a rotary dial for selecting primary test functions and function buttons (F1-F4) for navigating sub-menus and settings. The large color LCD provides clear readings and graphical representations.

Procediment general de proves:

1. Seleccioneu la funció: Rotate the main dial to the desired test function (e.g., INSULATION, LOOP, RCD, LOW OHM, VOLTAGE).
2. Connect Leads: Connect the test leads to the circuit or component under test according to the specific test requirements. Ensure all connections are secure and safe.
3. Configura la configuració: Use the F1-F4 function buttons to adjust test parameters (e.g., test voltage for insulation, RCD current for RCD tests) as needed. The display will guide you through available options.
4. Iniciar la prova: Press the 'TEST' button to begin the measurement.
5. Llegir resultats: Observe the results on the TFT color LCD display. For RCD tests, a PASS/FAIL indication will be provided.

Specific Test Functions:

• Resistència d'aïllament: Select the INSULATION function. Choose the desired test voltage (125V, 250V, 500V, 1000V). Connect leads to the circuit and press TEST. The device measures resistance up to 4000MΩ.

• Loop Impedance (L-PE Hi-Amp / No Trip): Select the LOOP function. The device supports fast high current loop tests and no-trip tests. Connect leads to L-PE and press TEST. The display will show impedance and other relevant parameters.

• Prova RCD: Select the RCD function. Configure the RCD type and current multiplier (x1/2, x1, x2, x5) using the function buttons. Connect leads to the RCD circuit and press TEST. The device will indicate PASS/FAIL and trip time. See Figure 6 for an example.

  

• Low OHM / Continuity: Select the LOW OHM function. Connect leads to the component. The device measures resistance and provides a continuity beeper for quick checks.

• Voltage Mesura: Seleccioneu el VOLTAGE function. The device can measure voltage between L-N, L-PE, and N-PE. Connect leads to the desired points. The Safe Earth Volt Touchpad can detect hazardous voltagés >50V.

  

The device supports data logging to SD memory and transfer via USB or wireless interface for further analysis.

Manteniment

• Neteja: Netegeu el dispositiu amb un suau, damp drap. No utilitzeu productes de neteja abrasius ni dissolvents. Assegureu-vos que el dispositiu estigui sec abans de guardar-lo o utilitzar-lo el proper cop.
• Substitució de la bateria: Replace batteries promptly when the low battery indicator appears to ensure accurate measurements. Always use 8 x 1.5V “AAA” batteries.
• Emmagatzematge: Store the tester in its carrying case in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries if storing for extended periods to prevent leakage.
• Cables de prova: Regularly inspect test leads for any signs of damage, such as cuts, cracks, or frayed insulation. Replace damaged leads immediately to ensure safety and accuracy.

Resolució de problemes

• El dispositiu no s'encén: Check if batteries are correctly installed and have sufficient charge. Replace batteries if necessary.
• Lectures inexactes: Ensure test leads are properly connected and undamaged. Verify that the correct test function and parameters are selected for the measurement. Clean the test points if they are dirty.
• Problemes de visualització: If the display is dim or flickering, check battery levels. If the issue persists, contact customer support.
• No RCD trip: Ensure the RCD is functional and correctly wired. Verify the test current and multiplier settings on the DT-6650.
