Product Name: Chitai CT 5601Y Clamp - on Ground Resistance Tester.

Purpose: It is used to measure ground resistance. In scenarios such as telecommunications systems, it can detect the grounding conditions of equipment. It enables non - contact measurement without the need for auxiliary electrode rods and without cutting wires.

Technical Principle: Based on the principle of electromagnetic induction, it measures the magnetic field generated by the current flowing through the measured grounding wire, and then calculates the ground resistance value. It also uses True Root Mean Square (TRMS) technology to accurately measure the current.

Performance: The measurable resistance range is 0.025Ω - 1500Ω, and the measurement range of leakage current in the grounding wire is 0.3mA - 30A. The diameter of the clamp is 23mm. It has a programmable upper and lower limit setting warning function, and will automatically emit a beeping warning when exceeding the limits. It can be set to automatically record within 1 - 255 seconds and has a memory capacity of 116 groups. It complies with CE CAT III 300V and CAT II 600V standards. The size is 257mm (length) x 100mm (width) x 47mm (height), and the accessories include 1 standard resistance detection circuit board.
