• Measurement range up to 2000 MΩ.
• Clear LCD display with 1999 counts.

2. Sicherheitshinweise

Beachten Sie stets die folgenden Sicherheitsvorkehrungen, um Verletzungen und Schäden am Instrument zu vermeiden:

• Lesen Sie das gesamte Handbuch bevor Sie das Gerät benutzen.
• Do not use the tester if it appears damaged or is operating abnormally.
• Ensure the circuit under test is de-energized and locked out before connecting the test leads.
• Geeignete persönliche Schutzausrüstung (PSA) tragen., including insulated gloves and safety glasses.
• Avoid touching the test leads or the circuit under test during measurement, especially when high test voltagEs werden angewendet.
• Discharge the circuit completely after testing before disconnecting the leads.
• Do not operate the tester in wet environments or in the presence of explosive gases or dust.
• Batterien ersetzen promptly when the low battery indicator appears.

4.2 Anschließen der Testleitungen

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. Bedienungsanleitung

5.1 Ein-/Ausschalten

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. Sicherheit gewährleisten: Verify that the circuit under test is completely de-energized and isolated from all power sources. Apply lockout/tagVerfahren durchführen.
2. Leads verbinden: 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. Select Test Voltage: 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. Test starten: Press and hold the 'TEST' button. The tester will apply the selected voltage and display the insulation resistance value on the LCD.
5. Messwert ablesen: 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.

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

6. Wartung

6.1 Reinigung

Wischen Sie die Oberfläche des Instruments ab.asing mit Adamp 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 Batteriewechsel

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 Speicherung

Bewahren Sie das Testgerät an einem kühlen, trockenen Ort, vor direkter Sonneneinstrahlung und extremen Temperaturen geschützt auf. Bei längerer Lagerung sollten die Batterien entfernt werden, um ein Auslaufen zu verhindern.
