使用保存注意事項 Cautions
1. 使用前，儀器需通電預熱15分鐘。The meter must be heating 15 minutes with the power on before use.
2. 適宜使用環境溫度0~40℃，相對濕度85﹪以下。Use in ambient temperatures of 0℃to40℃,humidifies of 85﹪R.H.
3. 本儀表校準時間間隔為一年。The meter alignment interval time is one year.
4. 注意防止震動和沖擊，不要在有超量灰塵和超量有害化學藥品和氣體等地方使用。Avoid using instruments in an area surrounded by vibrations of shock,dust,organic corrosive materiais or gas.
5. 若輸入信號伴隨高頻干擾，應在線里用低頻過濾器。If the input signal is superimposed with high-frequency noise,use a low-pass filter in the input signal line.
6. 輸入道線不宜過長。如被測信號輸出端與儀表距離不能縮短，請用雙絞屏蔽線，屏蔽層與信號低端相連。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. 若長期存放沒使用時，請每三個月通電一次，通電時間一次不少4小時。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. 長期保存應避開直射光線，宜存放在-10～70℃，濕度60﹪以下的地方。切勿和有機溶劑或油物接觸。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.
