Y8100 has been Discontinued. We suggest you go to the following page for possible replacements

Description

The F.W. Bell Y8100 is an exact replacement for the Fluke Model Y8100 clamp-on current probe.  It can be used with a digital multimeter or oscilloscope to measure dc, ac or composite (ac/dc) currents.  The ergonomic pistol shape sets the standard for hand-held comfort. Two ranges, 20 A and 200 A, produce a 2 V output at full current range.  An indicator light turns on when the battery voltage is too low for proper operation.
