Stotal = S 2 coil+ U 2 source
Example:
Assume we are driving the coil with the Fluke 5500A at 4A, 60 Hz (the clamp meter will see an effective current of 200A, 60 Hz) and we are calibrating a
Specification of effective calibrator current in coil bundle = ± (0.06% + 0.1A) = 0.11% Specification due to clamp Meter/Coil Interaction = ± (0.28% + 0.09A) = 0.325%
The RSS of these two specifications determines the total specification of the clamp/source combination:
Stotal =0.325%2 + 0.11%2 = 0.343%

Model 5500A/COIL
50-Turn Current Coil
Introduction
The 5500A/COIL is a 50-Turn Current Coil used as a tool for calibrating clamp-type current meters that
operate by two different principles—as current transformers (AC only), and by the Hall Effect (Both AC
and DC). It is impractical to calibrate 1000A rated current clamp meters using a 1000A source. How-
ever, by using the 50 turns of the 5500A/COIL in conjunction with a current source calibrator one can ef-
fectively 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.

UNFUSED. Exceeding current and voltage ratings can cause burn or fire hazard.
Using the Coil
Clamp-type current meters 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 re-
spect to the cable also affects the magnetic coupling between primary and secondary of the current trans-
former, which causes variation in reading of
the current meter. This is important to under-
stand in order to make the most accurate and
repeatable measurements. The base of the
5500A/COIL was designed so the current
clamp can be centered carefully on the coil,
minimizing operator error for best repeatabil-
ity. Calibration accuracy to specifications is
guaranteed only when proper clamp alignment
is made. The clamp current meter should be
centered as much as possible on the base dur-
ing calibration and verification. If the clamp-
type current meter has alignment marks, the
alignment marks should align the clamp with
the center bundled wire of the 50-Turn
5500A/COIL. (See Figure 1).
