TD1450 Simulated Standard Resistor
The TD1450 is a versatile high-precision calibration instrument capable of simulating both DC and AC standard resistances. It is specifically engineered for use in calibration laboratories, metrology institutes, production lines, and quality control environments.
Designed to support the calibration of loop resistance testers, DC resistance testers, ground bond testers, and other low-resistance measuring devices, the TD1450 delivers exceptional accuracy and stability under varying electrical conditions.
In addition to resistance simulation, the TD1450 also functions as a precision ammeter, enabling accurate DC and AC current measurements across a wide range — from low current to high-capacity test applications.
With selectable accuracy classes Class 0.05 and Class 0.02, high resolution, low noise circuitry, and a robust measurement architecture, the TD1450 is the ideal solution for advanced calibration requirements in electrical measurement systems.
