Fluke 10 & 50 Turn Current Coils
(item no. 1583963)
The Fluke 10 & 50 Turn Current Coils are used as an accessory device for calibrating clamp-type current meters. These clamp meters must operate by one of two different principles—either as current transformers (ac only), or by the Hall Effect (both ac and dc). It is impractical to calibrate 1000 A rated current clamp meters using a 1000 A source. However, by using the 50 turns of the 5500A/ COIL in conjunction with a current source calibrator, one can effectively multiply the current of the current source calibrator by a factor of 50 to support the calibration and verification of these clamp-type current meters.
