The 2558A precision DC calibrator is an easy-to-use, yet highly accurate instrument that can be used to calibrate analog power meters, thermometers, and temperature controllers that use a thermocouple or a resistance temperature detector (RTD).
The 2558A can output a wide range of AC voltages (1.00 mV to 1200.0 V) and currents (1.00 mA to 60.00 A) at frequencies of 40 to 1000 Hz. The accuracy (maximum error) is ±0.04% for AC voltage and ±0.05% for AC current, ensuring accurate calibration, and the stability is as high as ±0.005%/h. The easy-to-read digital display and dials for setting each digit are intuitive to use. The current output terminals can be used for all measurement ranges, which improves work efficiency by eliminating the need to change cables for a specific current level.
