Suited for on-site use in process industries, for diagnosing factory equipment, and for research and development, the CA100 is a highly portable, multi-function calibrator boasting of high accuracy. A single unit can be used to generate a dc voltage, dc current, resistance, temperature, and frequency. The unit provides a 24 vdc power supply for calibrating transmitters and for measuring dc voltage, dc current and resistance.With high accuracy, the device can calibrate transmitters and converters of 0.1% accuracy. A 24 vdc power supply provides a handy power source for transmitters to facilitate on-site calibration and maintenance of transmitters and converters.
