Direct Measurement for Conductive Surfaces

The CHUERA-780-1 is designed for applications where electrostatic voltage needs to be measured directly from a conductive surface. Its contact measurement method provides a practical solution for checking static voltage at specific test points during production, inspection, and ESD control procedures.

The extended sensing cable helps operators position the measuring probe without needing to move the main instrument close to the test area.

Compact Instrument with Flexible Probe Connection

The meter uses a handheld design with a separate sensing probe connected through a 60 cm cable. This configuration gives operators more freedom when working around equipment, fixtures, and confined areas.

The main unit measures approximately 165 × 80 × 28 mm, making it convenient to carry between different inspection locations.

Color Display for Quick Reading

A color display provides a clear view of measurement results and operating information. With a display resolution of 0.1V, the instrument can show relatively small changes in the measured voltage.

The control interface combines the display with physical buttons, allowing operators to move through operating modes and adjust settings during testing.

Measurement and Recording Functions

The CHUERA-780-1 supports a measurement range from -2000V to +2000V, with an accuracy of ±5%. Its sampling rate can be set within 1 to 10 measurements per second.

The built-in memory can store up to 10 × 10 records, making it possible to retain measurement results for later reference during inspection work.

Adjustable Alarm and Access Control

An adjustable alarm function can provide a visual reminder when the measured value reaches a preset condition. The instrument also supports password-based management, which can help control access to certain operating settings in production environments.

Rechargeable Power System

The unit uses a built-in lithium battery and operates from a DC 12V system. Charging and signal output are provided through a Type-C interface, offering a convenient connection method for routine charging and operation.
