The 2553A is designed for calibrating traditional voltage and current measurement devices, such as ammeters, voltmeters, digital multimeters, and DC wattmeters. In addition, the 2553A can calibrate thermometers and temperature controllers that measure via thermocouples or RTD sensors. The unit supports all commonly used thermocouple types specified by the IEC. Intuitive dials allow the user to adjust output values quickly and easily. The instrument also supports USB communication and mass storage, allowing it to be used as a system within a larger test bench or as a programmable output device.

The 2558A is a cost-effective, high-precision instrument capable of outputting a wide range of AC voltages and currents for the calibration of AC measurement devices such as analog wattmeters, power meters, clamp-on testers, and current transformers. Intuitive front panel controls and various computer interfaces enable the 2558A to be operated manually or become integrated into an larger system.

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

Accessories for digital power analyzers include various voltage and current transformers, clamp-on current probes, and a selection of test leads.
