说明 Notes: |
1.测量精度测试环境条件为:温度20±2度,相对湿度45-75% |
Ambient temperature of 20±2,humidity to 75%R.H,the measuring accuracy can be assured. |
2.任意量程的交直流电压、电流表均可按用户要求供货。 |
All range voltage,Ampere meter,can suit the demand of customer. |
3.配电流互感器其二次额定电流为5A,交流电压互感器其二次额定电压为100V,直流电流分流器其二次额定电压为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.根据用户要求仪表与电流互感器、分流器可以配套。 CTand DT may be equipped according to customers requirements. |

八、注意 CAUTIONS |
1.使用前,仪表需通电预热15分钟。The meter must be heated 15 minutes with the power on before use. |
2.适宜使用环境温度0~40度,相对温度85%下。Use in ambient temperatures of 0 to 40,humidity less than 85%R.H |
3.本仪表校准时间间隔为一年。The meter alignment interval time is one year. |
4.注意防止震动和冲击,不要在有超量灰尘和超量有害化学药品和气体等地方使用。 |
Avoid vibrations or shock,excessive dust,corrosive chemical materials or gas. |
5.若输入信号伴随高频干扰,应在线里用高频过滤器。 |
If the input signal is super imposed with high-frequency noise,use a low-passed filter. |
6.输入导线不宜过长,如被测信号输出端与仪表距离不能缩短,请用双绞屏蔽线,屏蔽层与信号低端相连。 |
Input wire should not be too long,If measuredsignal have to be faraway from the meter,pleas use 2-core shielded cable, |
and connect its shield lager to the LO side of the signal soure. |
