Inductive Load DC Resistance Rapid Tester



Detailed Introduction

Inductive Load DC Resistance Rapid Tester is centered on a high-speed microcontroller, adopting high-speed A/D converter and programmable current source technology, achieving excellent measurement results and highly automated measurement functions. It is a portable instrument used to measure various low-value resistances, especially inductive load low-value resistances.

Main Functions and Features of Inductive Load DC Resistance Rapid Tester

1. The ZGY-10A Inductive Load DC Resistance Tester uses a high-speed 16-bit A/D converter, ensuring stable measurement data and good repeatability.

2. Automatic programmable current source technology, with a total of 1000 current gears set in the current source, automatically controlled by the internal microcontroller according to the measured resistance, thus achieving a relatively wide measurement range without manual current gear switching.

3. Fast response speed. In the measurement state, the tap changer can be directly switched, and the instrument will automatically prompt, with the new resistance value displayed quickly.

4. Highly intelligent design with clever and advanced function settings, capable of automatically detecting faults such as loose test leads or broken wires.

5. Comprehensive protection functions, reliably protecting the instrument from back EMF impacts, with automatic discharge indication.

6. Can display measurement current and measurement time.

7. Intelligent power management technology effectively reduces internal heat generation.

8. Can store 120 measurement data records, print measurement data, and data is not lost on power failure.

9. All menus and operation prompts are in Chinese, intuitive and convenient.

Working Principle

      This instrument contains a constant current source that can generate DC current. When measuring resistance, constant current is fed from the I+ and I- terminals to the test object, generating a corresponding voltage value across the measured body. This voltage value is taken back from the V+ and V- terminals, amplified, and the resistance value of the test object is directly displayed on a four-digit LCD half-digital display.
