PZ Series Programmable Intelligent Electric Meters
1. PZ Series AC Test Meters
Overview
The series of meters adopt AC sampling technology,which can measure the current, voltage, power, powerfactor and electric energy parameters in the power grid separately.It can set the magnification through the panel membrane switch.The meters have RS-485 communication interface,adopt Modbus protocol;also can convert the power signal into a standard DC analog signal.The meters also have switching input/output,relay/alarm output,etc.

Wiring
Auxiliary power terminal
Signal input terminal
-Direct input of signal
-DC transmitter with isolation
Notes:
1. No isolation measures are taken inside the meter between the voltage signal port and the current signal port.When wiring,please note that the voltage difference between the negative terminal of the voltage signal and the negative terminal of the current signal must not exceed 5V.
2. In the actual use process,if the voltage or current signal is opposite to the wiring direction,the corresponding monitoring amount will be a negative value.When displayed,the corresponding display item will appear with a “-”sign.When the voltage and current signals are all positive or negative,the power will be expressed as positive,and the electric energy will be expressed as kWh.When the voltage and current are positive and negative,the power will be expressed as negative,and the electric energy will be expressed as kWh.The electric energy is measured by positive and negative separately,and does not affect each other.
3. If a DC transmitter is used,please inform us in detail of the transmitter performance and specifications before ordering.
Additional function terminal
Notes:
1. This wiring is for reference only，which is subject to the wiring diagram on the meter.
2. Relay alarm output and digital output DO2 multipexing.
