Chapter 1 Meter Overview
DZS100-4P is an advanced, smart single-phase DIN rail energy meter. It meters electric
parameters of single-phase current, voltage, power, energy, frequency, power factor etc.
with high accuracy. It is LCD display and also equipped with RS485 communication and
pulse output.
Its main functions are as follows:
◆Measure import active energy and export active energy;
◆Measure combination of active energy, which is equal to the sum of import active energy
and export active energy
◆Measure all instantaneous values of electric parameters, including voltage, current,
power, energy, frequency, power factor etc.;
◆LCD displaying voltage, current, power etc..
◆Automatically blocking and saving the blocked energy of last 12 months
◆Timing Records with saving last 10 times of recording moments
◆Loading data storage with recording data such as voltage, current, power, frequency,
power factor and active energy;
◆Compatible with DL/T645-2007, DL/T645-1997 and Modbus-RTU protocols.
Chapter 2 Specification & Technical Parameters

Chapter 4 Communication Interface
The meter is equipped with one communication interface. The settable baud rates of RS485
communication are 1200bps, 2400bps, 4800bps, 9600bps, 19200 bps. The default is
2400bps. The programming parameter settings and data reading can be completed with PC

with RS485 communication interfaces.
For Modbus Communication Protocol, when the last three digits of the bar code are less
than 256(decimal), the last three digits are the communication protocol addre ss for the
meter. For example, if the bar code is 170510201023, the communication protocol address
is 023.
While when the last three digits of the bar code are more than or equal to 256(decimal),
the last three digits of the bar code should be converted into hexadecimal, whose last two
digits are the Modbus communication protocol address.For example, if the bar code is
170510300920, the communication protocol address is 98(hexadecimal)/152(decimal).
Chapter 5 Meter Display & Operation
5.1 Operation and Buttons
The display interface is composed of LCD display screen, 3 buttons and 1 LED pulse light
indicator.
Press buttons “▲” and “▼”to cyclically switch interfaces of active energy, power,
voltage, current, power factor and frequency.
Press button “SET” to enter setting interfaces, in which PT/CT settings can be saved.But
the display data of voltage, current etc. does not make the appropriate multiplication.
