岛津LC-20A 氘灯刚换了一年,使用频率不高,突然有一天开机后氘灯不亮,电脑显示PDA Detector:Too low D2 lamp current.Check the connector of the D2 Lamp.If the connection is correct,exchange the D2 lamp.后来买了一个新的氘灯,安装上后仍然显示PDA Detector:Too low D2 lamp current.Check the connector of the D2 Lamp.If the connection is correct,exchange the D2 lamp.各位大神有没有遇到过的,是什么原因呢?
