4.2 Qawwa Inizjali

After installing the batteries, press the power button to turn on the device. The LCD display will illuminate, and a self-test sequence may run briefly before displaying the default measurement mode.

5. Istruzzjonijiet Operattivi

The MS5908C offers various measurement modes accessible via the FUNC button.

5.1 Volum Bażikutage u Kejl tal-Frekwenza

1. Plug the MS5908C into the electrical socket to be tested.
2. The device will automatically display the AC voltage u l-frekwenza.
3. Press the FUNC button to cycle through different voltage readings, such as phase voltage, neutral wire voltage, u voltage għall-art.

5.2 Impedance Measurement

To measure the impedance of the live, neutral, and earth conductors:

1. Ensure the device is plugged into the socket.
2. Press the FUNC button until the impedance measurement mode is displayed.
3. The device will show the impedance values for each conductor.

5.3 RCD/GFCI Testing

The MS5908C can test the trip time and current of RCDs and GFCIs.

1. Plug the device into a socket protected by an RCD/GFCI.
2. Press the FUNC button to select the RCD or GFCI test mode.
3. Press the TEST button to initiate the test. The device will simulate a fault condition and measure the trip time and current.
4. Observe the displayed results. A successful test indicates the RCD/GFCI is functioning correctly.
5. Reset the RCD/GFCI after the test.

5.4 Wire Drop Measurement (Artificial Load)

This function measures the voltage drop under specific artificial loads (5A, 8A, 10A).

1. Plug the device into the circuit.
2. Press the FUNC button to select the wire drop measurement mode.
3. Use the arrow buttons to select the desired artificial load (5A, 8A, or 10A).
