55XXA/COIL 50, 55XXA/COIL 10
Introduction
Use the 55XXA/COIL 50, 55XXA/COIL 10 (the Product or Coil) to calibrate clamp-type current
meters (clamp meters) that operate by two different principles - as current transformers (ac
only), and by the Hall Effect (both ac and dc). For example, it is impractical to calibrate
1000 A-rated current clamp meters with a 1000 A source. However, you can effectively
multiply the current of the current source calibrator by a factor of 50 to support the
calibration and verification of these clamp meters with the 50 turns of the 55XXA/COIL 50.

Example: A Fluke Calibration 5560A Calibrator supplies 13 A at 60 Hz to the 55XXA/COIL 50 generating an effective current of 650 A (50 x 13 A), 60 Hz). The 1-year specification of the Calibrator at 13 A is ±(0.07 % + 8 mA), which is equivalent to 0.13 % of the 13 A calibrator output. The total specification of the calibrator and the coil together as a percentage of the output: Specification of calibrator current = ±0.13 %... - Page 4 55XXA/COIL 50, 55XXA/COIL 10 Instructions Use the Coil Clamp meters and other current transducers often operate as current transformers, with differing degrees of magnetic coupling between primary and secondary that vary from meter to meter. The position of the clamp meter, with respect to the cable, affects the magnetic coupling between primary and secondary of the current transformer, which causes variation in the reading of the clamp meter.
