Typical Applications
An external current transformer may be used with the transmitter by
routing the secondary leads through the window opening. Use the
CR4340-5 current transmitter when using 5-Amp secondary instrument
grade current transformer. For additional details on current transformers,
see page 22.
The scaling factor may be changed by threading the primary current-
carrying wire several times through the window opening. The "actual"
measurement range will be the name plate range divided by the number
of wire passes. For example, the CR4340-30 has the name plate range
of 0-30 ACA. Two passes of the wire through the window opening will
then provide an effective range of 0-15 ACA (30÷2).
