au480 错误发生: 3200:sample short

Hello friend.
Sometimes, au480 reports an error: 3200 samples are short
Do not drop the needle down into the bottom of the sample tube.
Please help me fix it

注意下图的红圈位置

红圈位置所代表的含义是：
1: Sample surface not detected after sample aspiration descent
2: Sample slip-in amount insufficient after sample aspiration descent
3: Sample surface not detected after sample aspiration
4: Sample surface not detected for a moment after sample aspiration
5: Liquid level sensor ON after constant speed rise after sample aspiration
6: Stop at abnormal height after sample aspiration descent

你的问题反复出现1、6，表示样品杯识别错误或者样品杯或试管规格不正确，非标准样品杯。由于样品杯的错误，系统在预定的脉冲步进中没有找到液面。

全部为样品管，报警时为报告（2）。
我认为董事会要在跌倒之前检测到液体。 但我不知道如何解决

试管尺寸不标准或者传感器脏或损坏。

你好
错误报告是（2）：杯型（2）
我调整了参数: "Down stock for sample probe"
良好的接地。
但这是同一个问题，不是修复问题

We use copper mesh, the problem is solved

如果样品杯都是标准的情况下，样品针位置是否准确，针歪不歪，针尖是否在样品位的正中心，如果不在，当样品量很少的时候，针有可能扎到杯子的。其次，没有漏电、静电干扰的情况下，可以考虑液面探测线路板及其线路是否有问题。如果是标准试管的话，检查一下样品的量是否足够。最后需要考虑的是，光电耦合器是否有异物等干扰，定位不准确，样品针并没有下降到指定位置。

Au 8 series machine is full of liquid level induction error, copper screen shielding external electromagnetic interference, looks more beautiful than tin foil.

If such problems occur frequently, it is recommended to check the electromagnetic interference around the machine, such as centrifuge, high-power coil electrical appliances, compressor, etc. In Xinjiang, China, a case of au58 machine failure occurred after the relocation. Several engineers spent a week worrying about the error caused by the electromagnetic interference of the compressor of the reagent refrigerator behind the sample track.

换个新样本针，零低电压、样本如何。
Detailed error information /详细错误信息
1: Sample surface not detected after sample aspiration descent /吸样下降后没有探测到样品液面
2: Sample slip-in amount insufficient after sample aspiration descent /吸样下降后样品量不足
3: Sample surface not detected after sample aspiration /吸样后没有探测到样品液面
4: Sample surface not detected for a moment after sample aspiration /吸样后瞬间样品液面没有探测到
5: Liquid level sensor ON after constant speed rise after sample aspiration /吸样后样品针匀速上升时液面传感器
ON
6: Stop at abnormal height after sample aspiration descent /下降吸样后停止在异常高度
