【液相问题解决方案】仪器应用waters PDA Lamp energy low（灯能量低）错误

故障描述

• 接通电源后初步诊断时出现 Lamp energy low（灯能量低）错误

环境

• 2998 光电二极管阵列检测器

原因
1填充检测器池的溶剂具有 UV 吸光度。

2.超出灯使用寿命

解决方法
1.将低 UV 吸收的溶剂（如甲醇）输送到流通池中，然后打开电源。

2. 更换灯。部件号 201000273

SYMPTOMS

• “Lamp energy low” error occurs during initial diagnosis, after power-on

• "Lamp energy low" message

• Lamp has far exceeded the number of recommended hours

• PDA Shutter not found error message.

• Low lamp energy when check at 225 nm with water in flow cell.

ENVIRONMENT

• 2998 Photodiode Array Detector

CAUSE
The solvent that fills the detector cell has UV absorption.

Lamp life exceeded

FIX or WORKAROUND
Deliver a solvent with low UV absorption, such as methanol, to the cell, and then power-on.

Replace the lamp. part number 201000273
