Hello all,

Any idea what is causing low resistivity in ionograph?

Alcohol Content: Ionographs don't like to have the alcohol content too far off from 75%. If that happens, either way, your resistivity will be low.

Temperature: Ionographs don't like to be rushed. Stay focused on a proper warmup time. If you don't, your resistivity might be high and it might be low.

Run Time: Ionographs want you to Auto Time. If you don't, your resistivity will be low.

Flux: I know you would've told us about a flux change.

Thank you Dave! Alcohol was at 73.8%. I will check the rest.
