Review on 🔌 69020 Digital Coupler by YELLOW JACKET by Jump Robinson

I needed this sensor to remove two sets of mini studs. Everything went well the first time. On the second, the wss indicator went out and the units of measurement disappeared. When I was done, I turned the sensor off and on again and everything reappeared. I will be using it again in a few weeks to add freon and will try to remember to update the results.
