Product Overview
The CHUERA-4303D Wireless Leakage Voltage and ground resistance monitor is designed for continuous monitoring of electrical equipment where leakage voltage and grounding conditions need to be checked during production.
Instead of relying only on periodic manual measurements, the CHUERA-4303D provides real-time monitoring information directly on its 2.4-inch color display.
The monitor supports wireless communication for flexible installation and easier system deployment. LoRa communication is supplied as the standard configuration, while other communication options can be selected according to project requirements.
It is suitable for electronics manufacturing, ESD-controlled production areas, equipment grounding monitoring and other applications where electrical leakage and grounding conditions need to be monitored continuously.
Leakage Voltage and Ground Resistance Monitoring
The CHUERA-4303D can monitor two important electrical parameters:
Leakage voltage
Ground resistance
The leakage voltage measurement range is 0–500 mV, with a resolution of 0.1 mV.
The ground resistance measurement range is 0–20 Ω.
Monitoring both parameters in one device makes it easier for production and maintenance personnel to check equipment electrical conditions from a single monitoring point.
2.4-Inch Color Display
The monitor is equipped with a 2.4-inch color screen for direct viewing of operating data.
The screen can display monitoring information such as:
Different operating states can be distinguished through different display colors, allowing operators to identify abnormal conditions more quickly.
Wireless Communication
The CHUERA-4303D uses wireless communication to simplify installation and commissioning.
LoRa is the standard wireless communication method, while other communication options can be selected depending on the application.
Compared with systems that require extensive communication cabling, wireless transmission can make deployment more flexible, especially when multiple monitoring devices are installed across production areas.
Wireless signal strength can also be displayed dynamically on the monitor, helping technicians check communication conditions during installation and daily operation.
Three-Color Status Indication
The monitoring device uses a three-color indicator system to show its current monitoring status.
This allows operators and technicians to understand the equipment condition without needing to check detailed data continuously.
The visual indication is especially useful in production areas where several monitoring devices are installed at different workstations or pieces of equipment.
Local Data Storage
The CHUERA-4303D includes local data storage functionality.
If wireless communication becomes temporarily unavailable, monitoring data can continue to be stored locally in the device.
Once communication returns to normal, the stored monitoring records can automatically be transmitted to the PC system.
This helps reduce the risk of monitoring records being lost because of temporary communication interruptions.
Automatic Data Recovery
Temporary communication interruptions can occur in industrial environments.
For this reason, the CHUERA-4303D is designed to continue recording monitoring data locally during an interruption.
After communication is restored, the stored data can be automatically uploaded to the connected PC monitoring system.
This provides more complete monitoring records and makes historical data easier to review.
Online Upgrade Support
The monitoring device supports online upgrades.
This allows system maintenance and software updates to be carried out more conveniently without replacing the monitoring hardware.
The management software also supports intelligent IP locking, helping simplify device identification and network management when multiple monitoring units are deployed.

Why Monitor Leakage Voltage?
Electrical equipment used in electronics production may develop small leakage voltages because of insulation conditions, grounding conditions, power supplies or other electrical factors.
Even relatively low leakage voltage can become important in sensitive electronics manufacturing environments.
Continuous leakage voltage monitoring makes it easier for maintenance personnel to identify abnormal conditions while the equipment is operating instead of relying entirely on occasional manual measurements.
Why Monitor Ground Resistance?
A reliable grounding connection is an important part of electrical safety and ESD control.
Loose cables, connector problems or changes in grounding conditions can affect the resistance between equipment and ground.
By monitoring ground resistance continuously, the CHUERA-4303D provides a more direct way to identify changes in grounding conditions during production.
Designed for Centralized Monitoring
In production environments with multiple pieces of equipment, individual manual inspection can require significant time.
Wireless communication allows multiple monitoring points to be deployed more flexibly.
Together with local data storage, automatic data recovery and PC data transmission, the CHUERA-4303D can be used as part of a centralized monitoring system for factory equipment.
This is especially useful where historical monitoring records need to be reviewed or maintained over time.
