What's the resistance with respect to 0v on the zone wire with the zone wire removed from the panel screw terminal? With the zone wire removed from the terminal does it show any voltage (DC or AC) on the wire when measured against 0v? Next step is to swap zones and see if the problem remains or follows the wired devices. If it remains, replace the PCB. If it follows the wiring, then further investigation of the sensors and wiring is required. The Dimension firmware was changed at some point to only log marginal low/high res to the engineer log, so not surprising that these are not being reported to the arc.
