Connect the voltage cords and clamp sensors to the lines to be mea-
sured. To ensure proper connections for correct measurements, look at
t
he wiring configuration diagram (p. 83) while making connections.
5.2 Connecting to the Lines to be Measured
• When measuring three-phase lines, make connections to the lines to
be measured in the same sequence as the measurement channesl
(channels 1, 2 and 3).
• Although this one instrument can measure various wiring configura-
tions from single-phase 2-wire to three-phase 4-wire, it cannot mea-
sure single-phase power in three different systems.
Connecting voltage cords to lines to be measured
Securely clip the leads to metal parts such
as load-side screw terminals or bus bars.
Example:
Secondary side of breaker
L9438-55 Voltage Cord
