Functions
|
Measurement
|
measure DC voltage U, current I and power P,When the current input is hall sensor(4~20mA output),
the current only support unipolar metering.
|
|
|
Metering
|
measure current combined energy, forward energy and reverse energy,When the current input is hall sensor(4~20mA output),
the electric energy only support unipolar metering.
|

|
Time sharing
function
|
Each year can be divided into 4 time zones. Each time zone table can be set with 12 daily time periods and 4 rates (F1, F2, F3, F4 are
SHARP,PEAK,SHOULDER and OFF-PEAK).
The minimum interval of time periods is 15 minutes. Time periods can be set across zero（LCD Meter only)
|

|
Historical
data statistics
function
|
Count historical energy of last 12 months (energy of each rate)（LCD Meter only)
|

|
Switch input/output
function
|
PZ72 has two switch output and two switch input. PZ96 has two switch output and four switch input.
The switch output is relay output, which can realize remote control and alarm output.
The switch input can not only collect and display the local switch status information, but also realize the
remote transmission function through the RS485 of the instrument, namely the remote signaling function.
