A low-current precision DC, AC and DC/AC clamp-on measurement sensor

A low-current precision DC, AC and DC/AC clamp-on measurement sensor is described that can be used to make on-line calibration and measurement of DC, AC and DC/AC low-current in industry and laboratory. The sensor features current ratio accuracy grade of better than (5/spl sim/10)/spl times/10/sup -4/ for 10/spl sim/200 amperes current range, current resolution of 0.01 ampere, and transient response time of less than 1/spl times/10/sup -3/ second for the DC, AC and DC/AC clamp-on prototype.<>
