使用保存注意事项 Cautions
1. 使用前，仪器需通电预热15分钟。The meter must be heating 15 minutes with the power on before use.
2. 适宜使用环境温度0~40℃，相对湿度85﹪以下。Use in ambient temperatures of 0℃to40℃,humidifies of 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 using instruments in an area surrounded by vibrations of shock,dust,organic corrosive materiais or gas.
5. 若输入信号伴随高频干扰，应在线里用低频过滤器。If the input signal is superimposed with high-frequency noise,use a low-pass filter in the input signal line.
6. 输入道线不宜过长。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 measured singnal and meter is long,please use a 2-core shielded cable,and connect its outer shite to the LO side at a signal soure.
7. 若长期存放没使用时，请每三个月通电一次，通电时间一次不少4小时。If the digit meter relay is not used for a long time.Please connect power supply once every three months,not less than 4hours each time.
8. 长期保存应避开直射光线，宜存放在-10～70℃，湿度60﹪以下的地方。切勿和有机溶劑或油物接触。Long time for storing the meter in the shade with non high light-line with temperature of-10℃to70℃,and humidifies ofless than 60﹪.Dont contact with organic solvents of gas.
