Aloha SusanE,
Are you using two rods or one to get your readings?
It could be a couple things. I'd start with the two rod, yes/no reading, and ask the "Is the energy of this _______, greater than 5 for me?" Then work your way up or down.
There can be various things that skew your readings.
Hydrate, Tubes of Light, and practice sensing and testing often to develop the ability to focus your intention, while staying detached.
Much Love, Shawn
