Buffer reading from Keithley 2182A

[cdissanayake]

Hi,

I am using Keithley 2182A buffer to store voltages when the current changes in Keithley 6221. I have made the trigger between the two using the trigger link. I'm not using the delta mode here. When I execute the following vi it gives me error -110 and I found my buffer is empty too. I have attached the vi here. Really appreciate if someone can help to solve this problem. Thanks!

Hi cdis,

When I execute the following vi it gives me error -110

What does that error code denote? Did you read the device manual?

Check the commands you send to your device against the descriptions in the manual of your device…

Hi GerdW,

This error says "Command header error". I wrote these commands according to the manual. Sometimes I may missing something. I still can't find the solution for this. More importantly, I'm not getting anything in the buffer. Would be glad if you can help me with this. Thanks!

Hi cdis 

I see you write a complicated Buffer reading vi. If your request is only reading buffer from 2182A, That I suggest you download Keithley offical 2182A driver of Labview than modified it may more efficiency and reliable for your work. If you also have question, you can still to ask me ^^

※How to download driver see below：
