KEW6305 5.4

5.3 Using supplementary VT/ CT’s (not supplied with the instrument)

DANGER

● Never make measurement on a circuit in which electrical potential exceeds AC600V.

● Connect the Power cord to a socket outlet. Never connect it to the socket outlet of AC240V or

more.

● This instrument must be used on the secondary side of VT(transformer) and CT(current

transformer).

● Do not open-circuit the secondary side of a supplementary CT while it is energized because of

the high voltage generated at the secondary side terminals.

CAUTION

● When a VT or CT is used the measurement accuracy is not guaranteed due to several factors

namely phase characteristics and VT/CT accuracies.

The use of supplementary VT/CT’s may be required if the voltage/current values of the circuit under

test fall outside the instrument measuring range. In this case the value at the primary side of circuit

can be obtained directly by measuring the secondary side with appropriate an VT or CT installed in

the line under test as follows.

In this case, set the actual ratio of VT and CT to be used.

* VT ratio: “Setting 05”

* CT ratio: “Setting 06”
