TK6500 Arc Welding Machine AC DC Power Calibrator
TK6500 is a precision AC/DC power calibrator designed for on-site calibration of welding machines. It allows accurate calibration of internal ammeters and voltmeters without the need to disassemble the welding equipment, saving time and reducing the risk of damage. The device can handle high measurement currents up to 3 kA and offers selectable accuracy classes of 0.05 and 0.1, making it suitable for a wide range of industrial welding machines.
Equipped with high-resolution voltage measurement capability, TK6500 ensures precise verification of AC/DC voltage readings. The device also features a low temperature coefficient, minimizing measurement errors due to environmental changes. Its robust design supports reliable operation in challenging industrial environments with high humidity, temperature variations, and potential electrical interference.
TK6500 includes a user-friendly interface with digital display, intuitive controls, and computer program control via USB or LAN interfaces. This allows automated testing, data logging, and integration with existing quality control systems. Compact and portable, the device is easy to transport to different locations for on-site testing and calibration.
Key advantages include high measurement precision, wide current and voltage ranges, rapid response, and strong protection mechanisms such as overload, over-temperature, and short-circuit protection. TK6500 is an essential tool for welding equipment manufacturers, service engineers, and maintenance teams seeking fast, reliable, and accurate calibration solutions.
