5. Configuración
5.1 Instalación da batería
The T6125 requires 8 x 1.5V AA batteries (not included).
- Localice o compartimento da batería na parte traseira da unidade.
- Abra a tapa do compartimento da batería.
- Insira 8 pilas AA, asegurándose de polaridade correcta (+/-).
- Pecha a tapa do compartimento da batería de forma segura.
5.2 Conexión dos cables de proba
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. Instrucións de funcionamento
6.1 Encendido/apagado
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 Medición da resistencia de illamento
This function measures the insulation resistance of electrical equipment.
- Asegúrese de que o circuíto baixo proba estea desenergizado e descargado de forma 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).
- Manteña premido o PROBA button. The measurement will begin, and the resistance value will be displayed on the LCD.
- Soltar o PROBA button to stop the measurement. The instrument will automatically discharge the circuit.
- To hold the reading, press the ATENCIÓN 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
