1.3 Size and Wiring Terminals
The manual shows the size of the meter and details about its wiring terminals.
1.4 Connecting Terminal
It gives information about the connecting terminal of the meter.
2. Function Description
2.1 Electrical Parameter Measurement
It can measure various electrical parameters such as voltage, current, power, etc., with specific resolutions and accuracies. For example, voltage measurement has a resolution of 0.01V and an accuracy of ± 0.5%.
2.2 Metering Function
Supports bidirectional metering for active power, and can configure the calculation method of combined active power. It also supports different ways of reactive power metering and has a high - precision power consumption metering with a wide power range.
2.3 Demand Data and Maximum Demand (Optional)
Allows setting of the demand calculation cycle and method, and can calculate and record demand data for different types of power and their maximum values and occurrence times.
2.4 Multi - rate (Optional)
Supports four - rate or six - rate metering (depending on ordering requirements), and has multiple time zone and time slot tables.
2.5 Data Freezing
2.5.1 Freeze by Hour
Can record frozen data for at least 72 hours, with a default freezing time of 00 minutes per hour, and the freeze content includes forward and reverse total active electrical energy.
2.5.2 Daily Freeze
Can record at least 62 days of daily frozen data, with a default freezing time of 00:00 every day, and the freeze content covers various power and energy data.
2.5.3 Monthly Freeze
Can record up to 12 settlement cycles of data, with a configurable settlement time (default is 00:00 on the 1st day of each month), and the settlement content includes different types of power and energy data.
2.6 Event Record (Optional)
Supports recording various events such as power outage, closing, phase failure, voltage loss, overcurrent, and overload.
2.7 Communication
2.7.1 Local Communication
Provides one RS485 interface with a default baud rate of 2400bps, supporting DL/T 645 - 2007 and Modbus RTU protocols, and the Modbus register addresses can be customized.
2.7.2 Remote Communication
Has multiple options like 2G/3G/4G/WIFI/LoRa/RF, and supports multiple communication protocols, and can also be customized.
2.8 Information Indication
2.8.1 Pulse Indication
Has 4 high - brightness LED pulse indicator lights to show electricity consumption.
2.8.2 Liquid Crystal Display
Supports periodic rotation, button display, and optional screen backlight. The display items can be configured, with different page limits for wheel and button display.
2.8.3 Status Indicator
Several high - brightness indicator lights are used to show the working and display status, and different flashing patterns represent different meanings.
3. Transportation and Storage
The meter should be transported and stored in its original packaging, avoiding severe impact. It should follow relevant packaging standards, and be stored on shelves with a maximum stacking height of five layers in a non - corrosive environment.
4. After - sale Service
During the warranty period, the company will provide free repair or replacement for quality problems, provided that the user follows the specified operation specifications and the manufacturer's lead seal is intact.
5. Order No
The order number of the product has a specific coding rule. For example, "R" is fixed at 0; "X" indicates the communication method; "Y" represents functional options; "Z" shows the number of measurement channels; "C" indicates current specifications; "S" represents the SIM card situation; "NN" indicates the region.
