    Holec Zero Flux Current Transductor for Precise D.C. Measurement, type 5000 SH. This transductor has original factory specifications of 100 ppm absolute accuracy with an expected maximum error of 10 ppm change per month thereafter. In fact, as used in the Tevatron, the circuit has been altered such that the absolute calibration error is degraded to 0.1% (Dan Wolff, private communication). This error can be reduced by making the appropriate measurements.Google Scholar
