I was able to diagnose a problem at work with my xG3v1 today. Installing new equipment and one of the controls wasn’t working. Realized a solenoid wasn’t getting any power when I felt around it with the magnet. The electricians who ran the wires pulled out a jumper cable when they tried to operate the equipment which they weren’t supposed to do, only run the wires XD
Made a new jumper and bam, solenoid has power, can feel the EM field with the magnet, and the control works properly! Felt kind of cool
