DPM09 is a multimeter which measures and displays:

- 3 phase currents (I_L1, I_L2, I_L3).

- AC RMS values of 6 different voltages

  (V_L1-N, V_L2-N, V_L3-N, V_L1-L2, V_L2-L3, V_L3-L1)

- Frequency

- Over voltage (>120% of nominal V)/under

  voltage alarm (<80% of nominal V).

- Overload alarm/phase (>120% of CT rating).

Electrical Parameters:
