*1 Can be used only when the voltage is in a state of equilibrium.
In cases where “Three-phase four-wire system (2.5 element)” is specified,
the input current specification of 1 A AC is not applicable.
*2 Set the voltage range (150 V, 300 V or 600 V) according to the rated input
voltage to be measured.
*3 For Ethernet communication, the RS-485 communication interface is
exclusively for the Ethernet-serial gateway function.
