1 Introduction
The 9780 is an adaptor designed for use with Time Electronics multifunction calibrators, or
calibrated AC or DC sources. It enables accurate calibration and verification of a wide range
of clamp-type meters.
The unit is features twin coils built into a high insulation base plate, with a foam mat for
positioning the clamp meter being calibrated. Three heavy duty terminals with removable
caps provide connection from the calibrator to the clamp adaptor.
The black central terminal is the common negative connection. Then two red terminals allow
selection of the x1 or x50 turn coils. The low resistance test lead set supplied is made of
multi-strand (735/0.12 mm) oxygen free copper and is terminated with 8 AWG gold plated
ring and plug terminals.
When used with a high current multifunction calibrator, the 9780 provides a practical method
of calibrating clamp meters up to 1100 A. Models suitable for this application include the
5025E, 5025C, 5051+ calibrators, as well as the 7051+ CalBench module.
