有什么方法可以测量称重传感器？

我为延迟回复你道歉。
您是在扫描单个频道还是多个频道列表？
你在34970A中使用了什么多路复用器模块？
查看34970A数据表中的测量速度数据，了解您的速度。
要获得最大速度，必须使用4 1/2数字模式，固定范围和自动调零关闭。
10 ms是100 rdgs / sec。
34901A电枢继电器多路复用器的这些设置的最大扫描速度为60 rdgs / sec。
因此，如果您有5个通道，那么每个通道的测量重复时间为12 rdgs / sec / channel或83.3 ms。
使用34902A簧片继电器多路复用器，您可以达到210个通道/秒，因此您可以在您的时间限制内扫描两个通道。
使用单个通道和最快的设置，您可以达到500 rdgs / sec。
但请注意，对于更快的设置，精度和测量噪声抑制会降低。
我不知道“Ina128p和arduino”是什么。

  I apologize for the delay getting back to you.  Are you scanning a single channel or a list of multiple channels?  What multiplexer module are you using in the 34970A?

Look at the measurment speed data in the 34970A Data Sheet to find how fast you can go.  To get the maximum speed, you must use the 4 1/2 digit mode, with fixed range and autozero off.   10 ms is 100 rdgs/sec.  The maximum scanning speed with these settings for the 34901A armature relay multiplexer is 60 rdgs/sec.  So if you had 5 channels, that would be 12 rdgs/sec/channel or 83.3 ms measurement repetition time on each channel.   With the 34902A reed relay multiplexer, you can do 210 channels/sec, so you could scan two channels within the your time limit.

With a singel channel and the fastest settings, you can do 500 rdgs/sec.  But note that the accuracy and the measurement noise rejection decrease for the faster settings.  

I don't know what the "Ina128p and arduino" are.

非常感谢您的帮助。
我会按你的建议再试一次。
希望它可以解决我的问题:)

  Thank you very much for your help.
I will try it again as you suggest. Hope it could solve my problem :)

我们有类似的问题。
我们使用34970A和34901A 20通道多路复用器。
我们正在使用Bench Vue软件。
我们正在尝试对直流电压进行高速测量。
我们将分辨率设置为1个电源线周期，并将延迟时间设置为0秒。
我们只扫描一个频道。
我们发现测量之间的时间戳约为2 PLC。
换句话说，似乎有大约1PLC的死区时间。
我正在尝试进行零死区时间测量（或接近我可以得到的）。
任何建议？

  We have a similar problem. We are using the 34970A with 34901A 20 channel multiplexer. We are using Bench Vue software. We are trying to make a high speed measurement of dc voltage. 

we have set the resolution to 1 power line cycle, and the delay time to 0 seconds. We are scanning only one channel. 

What we find is that the time stamp between measurements is about 2 PLC. In other words, there appears to be about 1PLC of dead time. I am trying to do a zero dead time measurement (or as close to that as I can get). 

Any advice?
