50A color touch screen grounding wire group DC resistance tester for electrical instruments and meters

Equipment Introduction
In the power system, portable short-circuit grounding wires and personal protective grounding wires play a crucial role in preventing sudden incoming electricity to electrical equipment and lines, eliminating induced voltage, and discharging residual charges. In order to prevent unqualified grounding wires from entering the power system, our company has developed a group resistance tester for grounding wires in accordance with the requirements of the "Technical Standards for Portable Short Circuit Grounding Wires" and the "Preventive Testing Regulations for Power Safety Tools" issued and implemented by the State Power Corporation, providing services for the necessary product preventive testing of the power system.
Yangzhou Topu Electric Technology Co., Ltd. launched50A Color Touch Screen Grounding Wire Group DC Resistance TesterUsing a color touch LCD screen for display and operation, and adopting new power technology, the output current is stable, the output voltage is high, the measurement speed is fast, and the range is wide. It is suitable for testing various portable short-circuit grounding wires and personal protective grounding wires.

Features
1. This requirement is controlled by a high-speed microcontroller, with a high degree of automation and easy operation.
2. The instrument adopts a new power technology, with stable output current, high output voltage, fast measurement speed, wide range, suitable for testing various portable short-circuit grounding wires and personal protective grounding wires.
3. The instrument comes with a clock and a perpetual calendar, which can store 1000 sets of test data for customers to easily query at any time.
4. The device has complete protection functions, automatically protecting the internal power supply from overheating, effectively preventing damage to the power supply. At the same time, it has a voltage line reverse connection prompt function to prevent inaccurate test data caused by test line reverse connection.
5. The instrument adopts a 1024 × 600 LCD screen, with clear display under strong light and full touch screen operation.
650A Color Touch Screen Grounding Wire Group DC Resistance TesterEquipped with a thermal printer, it can print test data in real-time.
7. By utilizing intelligent power management technology, the instrument always operates in a low-power state, effectively reducing internal heat generation and saving energy.
