We use a Fluke 5522A and 5520 with scope pack for calibration in the electrical lab. with the ability to calibrate a wide range of products. The 5522A is a voltage calibrator, a resistance calibrator, a current calibrator and much more. It sources direct voltage and current, alternating voltage and current with multiple waveforms and harmonics, two simultaneous voltage outputs or voltage and current to simulate dc and ac power with phase control, resistance, capacitance, thermocouples and RTDs. The 5522A can also measure thermocouple temperature, and pressure using one of 29 Fluke 700 Series pressure modules we also have the added capability to calibrate oscilloscopes.
