Reliable Monitoring for ESD Workstations
The CHUERA-492 series is developed for workstations where operator grounding needs to remain under continuous supervision. The monitor checks the wrist strap connection during operation and provides a clear indication when the monitored resistance moves beyond the preset range.
This approach helps operators identify grounding issues during production instead of relying only on periodic manual checks.
Single-Channel and Dual-Channel Options
The series includes two configurations for different workstation requirements.
The CHUERA-492-1 is intended for one operator and provides a compact solution for individual ESD benches, inspection stations and dedicated assembly areas.
The CHUERA-492-2 is designed for two operators and provides two monitoring channels from one unit. It can be used on shared workbenches and production stations where two operators work within the same controlled area.
Adjustable Resistance Monitoring
The wrist strap monitoring resistance is specified from 750KΩ to 30MΩ, with the factory setting configured according to the application.
The adjustable monitoring range allows the equipment to accommodate different ESD workstation requirements while maintaining a consistent grounding inspection process.
Easy-to-Read Operating Status
The monitor uses indicator lights to show the current grounding condition. The specified status indications include green for OK, red for high resistance and blue for low resistance.
The simple visual arrangement allows operators and supervisors to identify an abnormal condition without navigating through complicated menus.
Compact Workstation Installation
The enclosure is designed for fixed installation near the operator's working position. Mounting flanges on both sides make it convenient to secure the monitor to an ESD workstation or related equipment.
Its compact form helps keep the monitoring device close to the work area without taking up unnecessary bench space.
External Alarm and Sensor Options
The CHUERA-492 series provides interfaces for additional workstation functions. External alarm indication can be connected when a more noticeable warning is required.
A photoelectric sensor can also be selected for applications that need operator presence detection or additional workstation control.
Grounding Connection Arrangement
The monitor is designed to work with ESD wrist straps and grounding connections used in controlled work environments. The available interface arrangement supports practical connection between the operator, wrist strap and workstation grounding system.
A suitable wrist strap can be selected according to the required workstation configuration.

Where the CHUERA-492 Series Can Be Used
The monitors are suitable for electronics assembly, PCB production, component inspection, repair benches, laboratories, testing stations and other areas where operator grounding is part of the ESD control process.
For individual workstations, the CHUERA-492-1 offers single-operator monitoring. For shared stations, the CHUERA-492-2 provides two-channel monitoring from one device.
Optional Wrist Strap
A single-circuit ESD wrist strap can be used with the monitor as an optional accessory. The strap provides the operator connection required for continuous grounding supervision.
