The RIC 422 reference impulse calibrator is a precision instrument of the highest performance class. It monitors and calibrates impulse measuring systems. All key impulse vvaveforms can be generated. The RIC 422 reference impulse calibrator is microprocessor-controlled. Entries are made via a numeric keypad and 10 function keys. The effortless and reliable setting of the instrument parameters is ensured by a large LCD. The RIC 422 complies with international standards IEC 1083 and IEEE 1122. A high-precision impulse circuit with an adjustable charging voltage generates the impulses. A peak...
