◎Twice or three times extended scale can be manufactured if the rated current of AC Ammeter is more than 1 A.
◎When the rated value is exceeded in DC Ammeter, connect the shunt and analog meter with 60 mV rated value.
◎When the rated valueis 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.

Customers are requested to provide the following information during order.

  1. 1. Model
  2. 2. Rated input value
  3. 3. Scale and Unit
  4. ※Receiving meter of DC 1 to 5 V (1 MΩ)needs power supply.
