5. Setup

5.1 Battery Installation

The T6125 requires 8 x 1.5V AA batteries (not included).

1. Locate the battery compartment on the back of the unit.
2. Open the battery compartment cover.
3. Insert 8 AA batteries, ensuring correct polarity (+/-).
4. Close the battery compartment cover securely.

5.2 Connecting Test Leads

Connect the test leads to the appropriate jacks on the front panel based on the measurement type. For insulation resistance tests, use the High Voltage Output jacks. For low resistance, use the Resistor jacks.

6. Operating Instructions

6.1 Power On/Off

Rotate the Gear Rotary Switch from the "OFF" position to any measurement function to power on the device. Rotate back to "OFF" to power off. The device will automatically shut down after 30 minutes of inactivity.

6.2 Insulation Resistance Measurement

This function measures the insulation resistance of electrical equipment.

1. Ensure the circuit under test is de-energized and safely discharged.
2. Connect the test leads to the High Voltage Output jacks (red to positive, black to negative).
3. Connect the other ends of the test leads to the insulation points of the equipment to be tested.
4. Rotate the Gear Rotary Switch to the desired insulation test voltage (e.g., 100V, 250V, 500V, 1000V, 2500V).
5. Press and hold the TEST button. The measurement will begin, and the resistance value will be displayed on the LCD.
6. Release the TEST button to stop the measurement. The instrument will automatically discharge the circuit.
7. To hold the reading, press the HOLD button during or after a measurement. Press again to release.

Figure 4: The T6125 offers a wide insulation test measurement range up to 2500V and 200.0GΩ.

6.3 Absorption Ratio (DAR) and Polarization Index (PI) Measurement

DAR and PI are used to assess the quality of insulation over time.

1. Follow steps 1-3 for Insulation Resistance Measurement.
2. Rotate the Gear Rotary Switch to the desired insulation test voltage.
3. Press the DAR/PI button to select the desired mode. The display will indicate "DAR" or "PI".
4. Press and hold the TEST button. The instrument will automatically perform the timed measurements and display the DAR or PI value.
5. Release the TEST button.

6.4 AC Voltage Measurement

To measure AC voltage:

1. Rotate the Gear Rotary Switch to the "ACV" position.
2. Connect the test leads to the circuit where AC voltage needs to be measured.
3. The AC voltage will be displayed on the LCD.

6.5 Low Resistance Measurement

For continuity or low resistance checks:

1. Rotate the Gear Rotary Switch to the "Ω" (low resistance) position.
2. Connect the test leads to the Resistor jacks.
3. Connect the other ends of the test leads to the component or circuit to be measured.
4. The resistance value will be displayed on the LCD.

7. Maintenance

7.1 Cleaning

Wipe the instrument with a damp cloth and mild detergent. Do not use abrasive cleaners or solvents. Ensure the instrument is completely dry before storage or next use.

7.2 Storage

When not in use for extended periods, remove the batteries to prevent leakage. Store the instrument in the provided cloth bag in a cool, dry place, away from direct sunlight and extreme temperatures.

• Storage Temperature: -20℃ to 60℃
• Working Conditions: 0℃ to 40℃
• Relative Humidity: 40% to 75%

8. Troubleshooting

If you encounter issues with your WOOXGEHM T6125, refer to the following common problems and solutions:

• No Power:
  • Check if batteries are installed correctly and have sufficient charge. Replace if necessary.
  • Ensure the Gear Rotary Switch is not in the "OFF" position.
• Inaccurate Readings:
  • Verify test leads are securely connected and not damaged.
  • Ensure the correct measurement function and test voltage are selected.
  • Clean the test points on the equipment being measured.
  • Check for external interference sources.
• "OL" or Over-range Display:
  • The measured value exceeds the selected range. Try a higher test voltage or a different range if applicable.
  • Ensure proper connection to the circuit.

If the problem persists, contact customer support.
