A. Ensure the batteries are fresh, if in doubt replace them. Use a quality brand. Do not use rechargeable types. Ensure the batteries are placed all the same way around, the positive end facing down. Do not mix brands or types as this could cause the batteries to leak. Make sure the O ring is in place at the top of the battery tube.

Ensure the probe is clean and you are testing your Truncheon Meter with a fresh conductivity standard.
A pinch of salt in a glass of tap water should give an arbitrary reading proving the Truncheon Meter is working.

If testing the Truncheon Meter in fresh water (tap water) you may not get a reading as water does not conduct electricity.
