Anyone tried using "Miner's Family Doctor"?

My mining rig started acting up, so I decided to grab a PicoBT multi-function hashboard tester. The customer support said I could try testing it on my own if I was careful, but honestly, I felt a bit nervous about messing it up. So, have you done it yourself?

Can you take a picture of that device with a piece of paper (your username + date you posted)? https://medium.com/@Kelly520/picobt-multi-function-hash-board-tester-user-guide-and-application-analysis-162d82a3191d

You have said well. The Op should provide the image of the device he claimed to buy and the image he showcased here is one of the image from the link you provided. And that means before the Op dropped the thread he has browsed about the device. I think the afternoon m of this thread is not to learn but for another thing because if really the Op bought the device, he would displayed the original image and not the internet pictures. And if really he wants to learn, the link you provided has everything the Op needs.

That's a universal hashboard tester or diagnostic tool to scan faults on the hashboard not only antminer hashboard are supported other well-known units are supported, including whatsminer. That one is expensive. It's worth buying if you have a big mining farm. If you have only Antminer units, you can buy only an Antminer test fixture that supports almost all Antminer units and is much cheaper. But since you already bought it and looking for manual then check this one https://www.zeusbtc.com/articles/information/4218-picobt-universal-miner-tester-user-manual
