◎Twice or three times extended scale can be manufactured if AC Ammeter of RMS type and moving coil type of analog meter.
◎W-2C, W-25 : When the rated value is exceeded in DC Ammeter, connect the shunt and analog meter with 100 mV rated value.
◎W-4B : When the rated value is exceeded in DC Ammeter, connect the shunt and analog meter with 60 mV rated value.
◎When the rated value is exceeded in DC voltmeter, connect the multiplier and analog meter with 1 mA rated voltage.
◎When the rated value is exceeded in AC Ammeter, connect the current transformer (CT) with analog meter with 5 A rated current.
◎When the rated value is exceeded in AC voltmeter, connect voltage transformer (VT) and analog meter with 100 V rated voltage.
