使用保存注意事項(xiàng) Cautions

1. 使用前，儀器需通電預(yù)熱15分鐘。The meter must be heating 15 minutes with the power on before use.

2. 適宜使用環(huán)境溫度0~40℃，相對(duì)濕度85﹪以下。Use in ambient temperatures of 0℃to40℃,humidifies of 85﹪R.H.

3. 本儀表校準(zhǔn)時(shí)間間隔為一年。The meter alignment interval time is one year.

4. 注意防止震動(dòng)和沖擊，不要在有超量灰塵和超量有害化學(xué)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(hào)伴隨高頻干擾，應(yīng)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(zhǎng)。如被測(cè)信號(hào)輸出端與儀表距離不能縮短，請(qǐng)用雙絞屏蔽線，屏蔽層與信號(hào)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(zhǎng)期存放沒使用時(shí)，請(qǐng)每三個(gè)月通電一次，通電時(shí)間一次不少4小時(shí)。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(zhǎng)期保存應(yīng)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(jī)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.
