5. Setup
5.1 Installazzjoni tal-batterija
The T6125 requires 8 x 1.5V AA batteries (not included).
- Sib il-kompartiment tal-batterija fuq wara tal-unità.
- Iftaħ l-għatu tal-kompartiment tal-batterija.
- Daħħal 8 batteriji AA, filwaqt li tiżgura polarità korretta (+/-).
- Agħlaq l-għatu tal-kompartiment tal-batterija sew.
5.2 Konnessjoni tal-wajers tat-test
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. Istruzzjonijiet Operattivi
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 Kejl tar-Reżistenza għall-Insulazzjoni
This function measures the insulation resistance of electrical equipment.
- Kun żgur li ċ-ċirkwit li qed jiġi ttestjat ma jkollux l-enerġija u ma jiġix skarkat b'mod sikur.
- 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).
- Agħfas u żomm il- TEST button. The measurement will begin, and the resistance value will be displayed on the LCD.
- Irrilaxxa l- TEST button to stop the measurement. The instrument will automatically discharge the circuit.
- To hold the reading, press the ŻOMM 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.
- Follow steps 1-3 for Insulation Resistance Measurement.
- Rotate the Gear Rotary Switch to the desired insulation test voltage.
