for wiring are 485A, 485B. The transmission medium of RS485 is shielded twisted pair
(STP). And the RS485 interfaces also can be used to the devices maintenance and
upgrading.

Energy Pulse Output (Pulse Constant is 9600):
The terminal PE-/PE+ are used for active energy pulse output.
D. Digital Input
Digital Input (Extension function): wiring mode as shown below, the actual number of digital
input depends on the actual energy meter model.
Chapter 3 Meter Display and Basic Operation

be used for displaying different measuring data and setting parameters though the four
buttons.
Introduction: Perform the following button operation, the meter displays the measured
