5. Configuració
5.1 Instal·lació de la bateria
The T6125 requires 8 x 1.5V AA batteries (not included).
- Localitzeu el compartiment de la bateria a la part posterior de la unitat.
- Obriu la tapa del compartiment de la bateria.
- Inseriu 8 piles AA, assegurant la polaritat correcta (+/-).
- Tanqueu bé la tapa del compartiment de la bateria.
5.2 Connexió dels cables de prova
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. Instruccions de funcionament
6.1 Encès/Apagat
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 Mesura de la resistència d'aïllament
This function measures the insulation resistance of electrical equipment.
- Assegureu-vos que el circuit a prova estigui desenergitzat i descarregat de manera segura.
- Connect the test leads to the High Voltage Output jacks (red to positive, black to negative).
- Connect the other ends of the test leads to the insulation points of the equipment to be tested.
- Rotate the Gear Rotary Switch to the desired insulation test voltage (e.g., 100V, 250V, 500V, 1000V, 2500V).
- Manteniu premut el botó PROVA button. The measurement will begin, and the resistance value will be displayed on the LCD.
- Allibera el PROVA button to stop the measurement. The instrument will automatically discharge the circuit.
- Per retenir la lectura, premeu la tecla MANTENIM 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
