Battery replacement for battery-only Igaging DROs?

[RJSakowski]

RJ, what size was the cap and can you elaborate a little on exactly how/where it was installed? I have a similar problem described here:

IGaging DRO EMI Problem

I just finished a restoration of an old family lathe and added many upgrades. Among them was a three-phase motor with VFD and two iGaging Absolute DROs. The build thread is here. https://www.hobby-machinist.com/threads/new-caretaker-of-two-12-craftsman-lathes.87335/ I can be pretty handy with...

I used a .05 mfd ceramic disk capacitor in parallel w2ith aa 10 mfd elctrolytic capacitor. I picked up the 3.5 volt trace at the USB socket and the ground trace sround the middle of the circuit board. I thought that I had a photo but I haven't been able to find it.

If your sensor is the same as mine, Vcc and Gnd are clearly marked on the circuit board. I tried to find a photo I took for someone else fighting a similar problem but came up short (it was awhile back).
