4.2 Connexion des cordons de test

Connect the red and black test leads to the corresponding input terminals on the tester. Ensure a secure connection to prevent inaccurate readings or hazards.

5. Mode d'emploi

5.1 Mise sous/hors tension

To power on the tester, rotate the function selector dial to any desired measurement function. To power off, rotate the dial to the 'OFF' position.

5.2 Performing an Insulation Resistance Test

Follow these steps to perform an insulation resistance measurement:

1. Assurer la sécurité : Verify that the circuit under test is completely de-energized and isolated from all power sources. Apply lockout/tagprocédures extérieures.
2. Connecter les prospects : Connect the test leads to the circuit or component you wish to test. Typically, one lead connects to the conductor and the other to ground or another conductor.
3. Sélectionner le volume de testtage: Rotate the function selector dial to the desired insulation test voltage (250V, 500V, or 1000V). Choose a voltage appropriate for the insulation rating of the circuit.
4. Lancer le test : Press and hold the 'TEST' button. The tester will apply the selected voltage and display the insulation resistance value on the LCD.
5. Lire la mesure : Observe the reading on the LCD. The unit will typically be in MΩ (Megaohms).
6. Discharge Circuit: Release the 'TEST' button. The tester will automatically discharge any residual charge in the circuit. Wait for the discharge to complete before disconnecting the leads.
7. Disconnect Leads: Once the circuit is safely discharged, disconnect the test leads.

Note: Always refer to relevant electrical codes and standards for acceptable insulation resistance values for specific applications.

6. Entretien

6.1 Nettoyage

Essuyez le c de l'instrumentasing avec publicitéamp cloth and a mild detergent. Do not use abrasive cleaners or solvents. Ensure the tester is completely dry before storage or next use.

6.2 Remplacement de la batterie

When the low battery indicator appears on the display, replace all 6 AA batteries promptly to ensure accurate measurements. Refer to Section 4.1 for battery installation instructions. Dispose of old batteries responsibly according to local regulations.

6.3 Stockage

Rangez le testeur dans un endroit frais et sec, à l'abri de la lumière directe du soleil et des températures extrêmes. En cas de stockage prolongé, retirez les piles pour éviter les fuites.
