Caution
Always use two magnets to hang the Product.
Voltage Test Leads
Voltage test leads are four-core, flat, test leads that do not tangle and
can be installed in tight spaces. On installations where the access to
Neutral is out of reach with the three-phase test lead, use the black
test lead to extend the Neutral lead.
For single phase measurements use the red and black test leads.
iFlexi Current Probe
The iFlexi Current Probe works on the Rogowski coil (R-coil) principle
that is a toroid of wire used to measure an alternating current through
a wire encircled by the toroid. See Figure 3.
