說明 Notes:
1.測量精度測試環境條件為:溫度20±2度,相對濕度45-75%
Ambient temperature of 20±2,humidity to 75%R.H,the measuring accuracy can be assured.
2.任意量程的交直流電壓、電流表均可按用戶要求供貨。
All range voltage,Ampere meter,can suit the demand of customer.
3.配電流互感器其二次額定電流為5A，交流電壓互感器其二次額定電壓為100V，直流電流分流器其二次額定電壓為75mV。
With AC CT,the second rated ampere is 5A,AC PT of the second voltage is 100V,DC dividerof the second rated voltage is75mA
4.根據用戶要求儀表與電流互感器、分流器可以配套。 CTand DT may be equipped according to customers requirements.
