INTRODUCTION

The MEWOI-HZ100A handheld circuit tester (hereinafter referred to as the instrument) is powered by a high capacity and high magnification lithium battery, with a compact design and handheld operation, making it easy to carry. A specialized testing equipment mainly used for measuring the contact resistance, loop resistance, and other micro ohmic resistance of switches, circuit breakers, transformers, and other equipment. The instrument display is shown in the following figure:

MAIN FEATURES

1. Adopting a 7-inch full color high-definition touch screen;

2. Large output current, wide testing range, multiple current options, maximum support for 100A current output;

3. The maximum testing time for full gear can reach 60 seconds, meeting national standards and on-site use;

4. Wide range (up to 0-50m Ω at 30A), high resolution of 0.1u Ω, with an accuracy of 0.5% within 2m Ω;

5. Equipped with complete protection functions such as open circuit protection and overheat protection;

6. It has the function of storing test data, which can save 1000 pieces of test data;

7. High capacity lithium battery power supply, capable of using 600 tests per charge (1 second test duration);

8. It has power management function, effectively reducing internal heating of the instrument and improving its service life.

9. It has Bluetooth function and can be configured with a Bluetooth printer (optional).
