A Practical Checkpoint for Personnel ESD Control

CHUERA-ST031 Human Body Electrostatic Comprehensive Tester is designed for routine electrostatic testing of personnel in ESD-controlled working environments. It combines wrist strap and ESD footwear verification into a single testing station, allowing operators to complete a grounding check before entering a protected area.

The unit uses a straightforward operating structure with a test controller mounted on an adjustable support. Its compact footprint makes it suitable for workshop entrances, electronics assembly areas, laboratories, and other locations where personnel grounding needs to be checked regularly.

Two Testing Functions in One Unit

The CHUERA-ST031 can be configured for both wrist strap and ESD footwear testing. The provided specifications indicate a wrist strap setting range of 750 KΩ–10 MΩ and a footwear setting range of 750 KΩ–100 MΩ.

This combined configuration allows different personnel grounding items to be checked at the same station, reducing the need for separate testing devices and simplifying routine inspection procedures.

Clear Status Indication

The tester uses three status conditions to make test results easy to identify. The green indicator represents a result within the configured range, while red indicators are used for results below or above the set limits.

This visual feedback helps operators quickly distinguish acceptable and abnormal test results without relying on complicated data interpretation.

Adjustable Installation Height

The support structure can be adjusted within a range of approximately 830–1430 mm. The adjustable design allows the testing station to be positioned according to the installation environment and user requirements.

The equipment is suitable for fixed testing points where a consistent standing position is preferred.

Fast Operation for Daily Inspection

CHUERA-ST031 is designed for simple and repeatable personnel testing. The equipment provides a dedicated test area for wrist straps and footwear, allowing operators to follow a consistent checking procedure during routine entry inspection.

The system also includes a low-battery indication function. When the battery level is low, the indicator can remind users to recharge the equipment in time.

Test Result Reference

According to the supplied test data, footwear measurements below 740 KΩ are indicated as Fail Low, while values within the configured pass range are shown as Pass. Higher resistance values can trigger the Fail High indication.

For wrist straps, the supplied test results show a similar three-state indication, with values below the lower limit identified as Fail Low and values above the upper limit identified as Fail High.

Actual acceptance limits should be configured according to the user's ESD management requirements and applicable testing procedures.

Suitable Working Environments

CHUERA-ST031 can be used at entrances to ESD-controlled workshops, electronic assembly plants, PCB production areas, laboratories, component manufacturing facilities, and other workplaces where personnel grounding verification is required.

It is particularly suitable for locations that need a dedicated standing test point with straightforward visual result indication and adjustable installation height.
