Handheld circuit resistance tester -100D

1Product Introduction

Handheld circuit resistance tester -100DThis instrument is a high-precision, digital switch detection instrument carefully developed based on the latest power implementation standard DL/T845.4-2019 of the People's Republic of China, leveraging its own technological advantages. This testing device is suitable for high-precision measurement of contact resistance (loop resistance) of high-voltage switches, and is also applicable to other occasions that require high current and micro resistance measurement. The instrument has accurate measurement data, stable performance, and meets the requirements of on-site high-voltage switch maintenance and high-voltage switch factory circuit resistance testing by the power and supply departments.

Handheld circuit resistance tester -100DTo support traditional circuit resistance testing, it is necessary to disassemble one side of the grounding busbar on both sides of the tested switch to avoid the influence of grounding network shunt.

IICharacteristics and main functions

1) Adopting a high brightness 7-inch color LCD screen, the display is clear, the human-machine interface is friendly, and it is visible under sunlight.

2) The whole machine is controlled by high-speed chips, with a high degree of automation and simple operation.

3) The maximum output current can reach 100A, with fast testing speed and high measurement accuracy.

4) The protection function is complete, with overcurrent, short circuit, and overheating protection functions.

5) Overheating protection: battery overheating and power device protection, threshold: 70 ℃;

6) Battery over discharge protection: One battery level will enter battery protection mode, prohibiting all tests.

7) Built in large capacity non-volatile memory, capable of storing 512 sets of data, supporting viewing and exporting.

8) Built in high-precision clock, real-time display of time.

9) It has USB storage function.

10) Voice broadcasting function, automatically broadcasting measurement results after testing is completed.

11) Integrated with mainstream wired (RS232) and wireless communication (Bluetooth, WIFI) functions, convenient for data uploading and remote control.
