Thank you for taking the time to provide feedback. We apologize that you did not get a reply, but we can't find that we ever received a message. You did have phone conversations with a couple of us today so we could try and fix any outstanding problems. You have a resistance around 20 ohms and want to resolve changes of around 0.0005 ohms. We looked and discussed and agree that is beyond the ability of the LJTick-Resistance-1000, even with the T7-Pro. The circuit you have set up yourself is working well for you and improving on that would likely require a custom circuit involving at least 1 precision op-amp. Not getting a reply is never okay. Whether you use direct email, comment in offline chat, or our contact form, they all result in an email to our main support box. We respond to most emails the same day, so if you have not heard back in a day or 2 there is definitely some problem. If this ever happens to anyone please contact us again and if you don't hear back quickly get on chat or call us to figure out what is wrong with the email. We really hate that someone would ever think they contacted us and then get no reply. As of this writing, our live chat hours are Monday through Friday from 9-11 am and 2-4 pm, Denver time. Yes that is only 50% of business hours, but we find that this schedule allows us to efficiently provide real support (Colorado engineers) and never use a chat robot or overseas support.

Sorry about your troubles Stefan. We are communicating directly and working on resolving this as best we can, but there was a misstep on our part here. The T8 is in "Early Release" status. Most aspects of the T8 are fully functioning, but some are not. A device like the T8 with 8x 24-bit simultaneous isolated analog inputs, is needed right now for some customers, and the features that are not fully supported are not a problem for many of these customers, so we are excited to get T8s in these customers hands during the Early Release phase. We have a T8 Release Status page, but we also have a rule that during Early Release no T8 ships until someone from our engineering department has talked to each customer about their requirements to make sure the T8 is right for them. Unfortunately that last step did not happen in this case, so we have now implemented further internal rules & awareness to make sure it does always happen going forward.
