1.故障现象按动AA—BG键后(工作波长为350mμ以下),显示故障号码“E71”。表明氘灯和空心阴极灯能量不匹配,仪器不能进入背景校正的工作方式。有时当空心阴极灯的电流太小时,氘灯的发射强度比空心阴极灯强度大,仪器不能自动调整氘灯电流,此时也会出现“E71”的错误号码,只要适当增大空心阴极灯电流,两电流的发射强度即可匹配。上述故障不属此类。
1. Symptom After pressing the AA-BG key (the working wavelength is 350mμ or less), the error number “E71” is displayed. Deuterium lamp and hollow cathode lamp that does not match the energy, the instrument can not enter the background correction mode of operation. Sometimes when the current of the hollow cathode lamp is too small, the emission intensity of the deuterium lamp is greater than the intensity of the hollow cathode lamp. Therefore, the instrument can not automatically adjust the deuterium lamp current. In this case, the error number of “E71” will also appear as long as the hollow cathode lamp current , Two current emission intensity can match. The above failure does not belong to this category.
