My (one month old and working fine) G90 rack unit keeps failing a portable appliance test on the basis of poor earth continuity. I'm in Aus and many venues will require a PAT tag before they let you plug in
The resistance I am measuring between the earth pin on the plug and say a random screw on the case is less than 0.5 ohm. Is there something I'm missing here, is the chassis not solidly earthed? The amp and compressor in the same rack pass fine.
Input welcome and thanks in anticipation.
