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 0.125 A up

to 50 A in a frequency range of 40 Hz to

5 kHz. The clamps are approved for the

required installation category.

The current clamps are designed for use on insulated conductors. For using it with uninsulated conductors you have to

switch off before attaching the clamp. The application of the clamps on uninsulated conductors is limited to 600 V ac r.m.s.

or dc to ground and frequencies below 1 kHz.
