5.2 Connecting to the Lines to be Measured
82
Connecting clamp sensors to lines to be measured
OK
Be sure to attach each clamp around
only one conductor.
Correct measurement cannot be
obtained if a clamp is attached around
more than one conductor.
(Example: Model 9660)
Make certain that the
current flow direction
arrow points toward the
load.

Current Flow Direction Arrow
To measure load current
To measure leakage current
Single-phase, 2-wire line: clamp around both wires
Single-phase, 3-wire line: clamp around all three wires
Three-phase, 3-wire line: clamp around all three wires
Earth ground: clamp around just the one line
Make certain that the
current flow direction
arrow points toward the
load.
