The Model 2560A is a simple, precise and cost effective solution for calibrating DC measuring instruments such as analog meters, thermometers, temperature transmitters and data loggers

The 2560A Precision DC Calibrator offers high voltage and high current generation and intuitive operation for the analog meters calibration.

Wide output range of voltage and current generation
Dials and switches for each digit and function
High accuracy, stability, and resolution
Various effective functions for analog meters calibration.

With output ranges of 100 mV to 1000 V and 100 µA to 30A, plus 10 different types of Thermocouples and Pt100 RTD, the 2560A can effectively solve the calibration requirements for DC Analog Meters and various temperature measuring instruments and controllers.
