TD1540 DC Shunt Verification Device
The TD1540 is a professional-grade calibration system designed specifically for verifying and testing DC shunts with exceptional accuracy and stability. Composed of a precision DC voltmeter and a high-performance DC standard large-current source, this system ensures reliable calibration for a wide range of measurement tasks.
The TD1540 is widely used in metrology laboratories, power utilities, manufacturing units, and quality assurance departments. With high short-term stability, selectable accuracy levels (Class 0.05 and Class 0.02), and support for multiple current ranges up to 500 A, it provides consistent and repeatable results.
Its advanced shielding design helps minimize electromagnetic interference, ensuring high measurement integrity even under demanding test conditions. Compact, portable, and engineered for long-term stability, the TD1540 is an ideal calibration solution for industrial standards compliance and laboratory-grade precision.
