Anybody seen an AMPLOC KEY100 Hall Effect sensor read significantly low? The two I installed are reading low, around 2/3 of normal. I have a third one (spare) that is reading correctly. The two bad ones were in 3D printed ABS holders so I took them out and put all three in series on the power positive lead of my ground power connection. Without powering down the airplane, I tested all three one at a time on the same GEA 24 channel by moving the connection to each one, testing with a low load and then a high total load. Accounting for the zero offsets, I read 8.2A, 8.2A, and 12.8 A. I wired up a shunt and it reads 12.6 A while the ammeter on my external power supply reads 13.8 A. Is there a chance the calibration could have been permanently altered by the steel screws I used to mount the holder? Or maybe a magnetic screwdriver bit?
I called Amploc and they said they would replace them if defective, I'll send them in.
