*Voltage transformer (VT) is required when you measure a load
with voltage over 240VAC (Allowable measurement voltage).
*Secondary voltage rating of VT is 110V.

<Using a commercial CT with the secondary side current 5A>
・1 to 4000A (Set with setting mode)
*Use CT with secondary side current of 5A when measure 600A or
more.
