Product Name: HCL5100C Loop Resistance Tester
Category: High Voltage Equipment Comprehensive Test Series

Detailed Introduction

According to the requirements of DL/T 596-2005 Preventive Test Procedures for Power Equipment and DL/T 845.4-2004 General Technical Conditions for Resistance Measuring Devices Part 4: Loop Resistance Tester and other relevant power industry standards, the test current for contact resistance of various circuit breakers and disconnecting switch equipment shall not be less than 100A.

In response to this, our company has designed and developed the HCL5100C new generation of high current output micro-ohm resistance test handheld instrument, which is suitable for testing the contact resistance of the main contacts of high voltage switch equipment, the DC resistance value of high and low voltage cable lines, etc., which greatly reduces the labor intensity of on-site testers.

Functional features

※ The instrument is powered by an internal lithium battery, which solves the problem of being unable to test on site due to lack of working power supply;

※ The test process is controlled by a microcomputer, automatically completing self-calibration, steady current judgment, data processing, and resistance display;

※ It has overcurrent and short-circuit protection functions, and can complete rapid disconnection;

※ The internal test circuit has a temperature detection protection function, and the temperature protection threshold is 50°;

※ It has a test alarm function: the test process is accompanied by a buzzer alarm sound;

※ It has the characteristics of simple operation, high precision, anti-interference, shockproof, and easy to carry;

※ It uses a 5-inch 800*480 high-brightness LCD display with a brightness of up to 900nit, which is clearly visible in the sun;

※ It has a built-in large-capacity non-volatile memory, which can store 500 sets of measurement data and can be imported into a USB flash drive for storage;

※ It has a built-in high-precision real-time clock function: it can calibrate the date and time;

※ Built-in 6000mAh/75.6Wh large-capacity imported lithium battery, which can meet the needs of long-term on-site testing.
