Connecting Clamp-on Probes
When connecting a clamp-on probe to the CW240 main unit, connect the plug of
the clamp-on probe so that the groove in the plug agrees with the guide in the
CW240 main unit (that the H and L polarities are correctly connected).
●
Types of Clamp-on Probes
Clamp-on probes that can be connected to the CW240 are available in the
following seven types. The CW240's current range setting changes depending
on the clamp-on probes in use.
CW240 Current Range
