Product Profile of Combimeter [true Rms Digital 7 In 1 Meter-three Phase]

Automatic electric ltd. Is engaged in manufacturing electrical instruments, power systems and instrument transformers in india. The company has been accredited with an iso 9001 certification. The combimeter is a 3 phase, rms digital 7 in 1 meter. The meter incorporates micro-controller system, which samples voltage and current signals and computes voltage, frequency, current, active power and reactive power & apparent power. The following are its unique features:

1. power factor is computed by power division method.
2. parameters are displayed on four digit, seven segment, led display.
3. mode push button allows selection of respective phases [l1, l2, l3] & system
4. ``select` push-button is used to select various parameters
5. one meter replaces minimum of eleven meters on panel.
6. `0.000` indication when auxiliary supply is on.
7. `pfer` indication when input current is not applied.
8. `erlo` indication when input signal voltage is not applied. 9. frequency indication on ? mode when any one of phase voltage signal is absent.
10. sign indication depend upon current direction,
11. combimeter is 3 ph - 2 el - 3w / 3 ph - 3 el - 4 w type
