User Manual for
Rail‐Mounted Multi‐Circuit Power Meter
Apply to：PD194Z‐E14

1.Overview
Rail‐mounted multi‐circuit power meter can measure parameters of multiple three phase or
single phase power grid such as voltage, current, power, frequency, energy, demand, extreme
value, total harmonic distortion, 2nd‐31st harmonics, voltage and current unbalance and
multi‐rate electric energy measurement. The maximum measurement circuits of PD194Z‐E14 is
four three‐phase circuits or twelve one single‐phase circuits. The meter adopts access mode of
external current transformer and modular design which is convenient for user to choose
different functions to meet different requirements at field.
