Features and Construction

The meter is built around core features that enhance usability and safety during electrical testing. Its digital display and automatic operation reduce user error, while the burn-proof construction adds protection in demanding environments.

High-definition LED Display

The display provides clear, readable digits without ghosting, ensuring accurate readings at a glance. The backlight function illuminates the screen in low light, and the flashlight helps illuminate test points in dark spaces, making the tool versatile for various work conditions.

Fully Automatic Test with One-key Measurement

With automatic gear selection, the meter handles voltage, current, or resistance tests without manual adjustment. Simply press the single key to start measurement, saving time and reducing complexity, especially for non-specialist users.

Compact Size and Bracket Design

Measuring 132x25x64mm, the meter is small enough to fit in a pocket or tool pouch. The back bracket allows it to stand upright on a flat surface, freeing both hands for probe placement during testing.

Uses and Placement

Designed for general users, this meter is suited to hydropower engineering, electrical maintenance, and DIY tasks. Its automatic function and portable form factor support both professional and occasional use.

Hydropower Engineering and Electrical Work

In hydropower settings, the meter’s burn-proof construction and automatic testing provide reliable measurements for checking circuits, outlets, and components. The backlight and flashlight are particularly useful in control rooms or basements with limited lighting.

Everyday Home Use

For home electricians, the one-key operation removes the learning curve of manual-ranging meters. Testing batteries, fuses, or appliance continuity becomes quick and hassle-free, with the compact size making storage easy in a toolbox drawer.

Benefits and Buying Value

The primary value of this meter lies in its simplicity and safety features. Automatic operation saves time and reduces errors, while the burn-proof casing and built-in lighting enhance practical usability.

Automatic Operation Reduces Error

By eliminating manual gear selection, the meter minimises incorrect range settings that can lead to inaccurate readings or accidental damage. The one-key measurement is ideal for users who want straightforward, reliable testing.

Low Maintenance and Practical Design

With no moving parts for gear changes and a robust burn-proof case, the meter requires minimal upkeep. The integrated backlight and flashlight eliminate the need for separate work lights, making it a self-contained tool for dark or confined spaces.
