Handheld circuit resistance tester

Overview

Handheld circuit resistance testerbased onIECHigh precision digital switch detection instruments developed and manufactured according to standards and relevant national regulations. The instrument is equipped with a high-power, high stability constant current switching power supply, which can accurately measure micro ohm level contact resistance. Widely used to measure the contact resistance, loop resistance, and contact resistance of various high current switches, as well as wires, cables, and welds.

Performance Characteristics

The test current is high and meets the national standard requirements for testing contact resistance.

High output voltage, wide testing range.

The test current comes from a high-precision high current constant current source, and the test is fast and accurate.

The use of four terminal wiring method effectively eliminates the influence of test line resistance on the test results Ring.

Fast testing speed,2Display test results in approximately seconds.

This instrument adopts320*240True ColorTFTTouching the LCD screen, it is still clearly visible under strong light, and the operation interface is displayed in both Chinese and English.

The data measured by the instrument can be printed in real-time, stored inside the instrument, or exported toUPlate,

And it comes with a real-time clock, making it easy for users to query, analyze, and manage test data.

This instrument hasRS232Connected to Bluetooth data interface for easy communication or operation with the upper computer (Bluetooth requires an adapter)

Intelligent power management technology ensures that instruments always operate at their minimum power state, effectively reducing internal heat generation, thereby reducing power consumption and saving energy.

Full voice broadcast throughout the entire process.

Automatically shut down within five minutes without any operation.
