五、注意 CAUTIONS (1)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 mixes with the high-frequency interference,a high-frequency filter should be used in the wire. (2)当电压与电流表共用一个电源极易造成数字表损坏,各表头应隔离供电. They are easy to be damaged when the Voltmeter and Ammeter share power supply,so the power supply for the two should be isolated . (3)存放温度:-10℃ ~ +70℃,长期保存应避免直射光线.每三个月通电一次,通电时间不少于4小时. Storage temperature:-10℃~+70℃, avoid light point -blank when long-time storage,please connect it to the power once every three months and power-on time shouldn't be less than
