FOUR : NOTE

1、The meter must be heated 15 minutes with the power on before use. （使用前，儀表需通電15分鐘）

2、Avoid vibrations or shock，excessive dust and noxious gas.（注意防止震動和沖擊，不要在有超量灰塵和超量有害氣體的地方使用）

3、Input wire should not be too long，please use 2-core shielded cable if the measured signal input terminal is more long.（輸入導線不宜過長，如被測信號輸入端較長時請使用雙絞屏蔽線）

4、If the input signal is super inposed with high-frequency noise, use a low-frequency filter. （若信號伴隨高頻干擾，應在線里使用低頻過濾器）

5、If the meter won’t be used for a long time ,please connect power supply every three months, not less than 4 hours each time.（長時間存放未使用時，請每三個月通電一次不少于4小時）

6、Long time for storing the meter should be in the shade ,with the environment temperature is -25℃~55℃,the relative humidity :≤93%,and non-corrosive gas sites.（長期保存應避開直射光線，宜存放在環(huán)境溫度：-25℃~55℃，相對濕度≤93%  無腐蝕氣體場所）

7、If the meter no display that you should check –up the auxiliary power firstly , and the voltage should be fall within the prescribed limits.（如儀表無顯示，應先檢查輔助電源，電壓是否在規(guī)定范圍內(nèi)）

8、If display is abnormal state, please check-up if the input signal working correctly and the signal terminal tightened or not.（如顯示不正常，檢查輸入信號是否正常及信號接線端是否擰緊）

9、Except the PT has enough power , otherwise you can not use the PT signal as auxiliary power at the same time. Then can be ensure the meters working as normal.（除非PT有足夠功率，否則不能使用PT信號同時做為輔助電源，以保證儀表正常工作）

10、The screw of current terminal in the CT circuit must be tightened, ensure the in-wire and out wire be reliable , so as not to cause malfunction.（CT回路中的電流接線端子螺絲務必擰緊，保證進/出線接觸可靠，以免產(chǎn)生故障）
