*1 In case you measure the larger voltage than instrument rating, please use the transformer (VT) for the instrument. (For single-phase 2-wire and three-phase 3-wire: The measurable range is the primary voltage of VT up to 110000V and the secondary voltage of VT up to 220V) (For single-phase 3-wire: Cannot measure the voltage) (For three-phase 4-wire: The measurable range is the primary voltage of VT up to 110000V and the secondary voltage of VT up to 220V) The transformer of star-delta connection and delta-star connection can't measure correctly because of the phase shifting. Please use transformer of same wire connection.

*2 In case you measure the larger current than instrument rating, please use the transformer (CT) for the instrument. (The measurable range is the primary current of CT up to 30000A, the secondary current of CT is fixed to 5 A.)
