These current clamp sets have been
designed for applications with Fluke
1735 and Fluke 1740 series products for
accurate non intrusive measurement of
ac currents. Using latest technologies
(integrated memory for calibration data)
provides current ranges from 0.5 A up to
200 A in a frequency range of 40 Hz to
5 kHz. The clamps are approved for the
required installation category.
