5. Nastavitev
5.1 Namestitev baterije
The T6125 requires 8 x 1.5V AA batteries (not included).
- Poiščite predal za baterije na zadnji strani enote.
- Odprite pokrov prostora za baterije.
- Vstavite 8 AA bateriji in pazite na pravilno polarnost (+/-).
- Trdno zaprite pokrov prostora za baterije.
5.2 Priključitev merilnih vodnikov
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. Navodila za uporabo
6.1 Vklop/izklop
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 Merjenje izolacijskega upora
This function measures the insulation resistance of electrical equipment.
- Ensure the circuit under test is de-energized and safely discharged.
- 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).
- Pritisnite in držite TEST button. The measurement will begin, and the resistance value will be displayed on the LCD.
- Spustite TEST button to stop the measurement. The instrument will automatically discharge the circuit.
- Za zadržanje odčitka pritisnite PRIDRŽI 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.
