Pinpoint PH Monitor Fluctuation

[Salty Irishman]

Decided to use limewater to help with ph/calcium and purchased a pinpoint to keep a close eye on things. After carefull calibration and positioning the probe, it seems if I move the lead wire and nothing else the readings change from 8.1 to 8.0 and vice versa. Has anyone experienced this? Seems I need more calibration fluid to see which position of the wire gives the correct reading. Any insight would be helpful.

you need to move the lead wire away for any electrical field.. or atleast as far away as you can ....it sound like that is what the problem maybe

I thank you for the reply and have to believe your exactly right. The lead wire was resting on the power cord to a ballast giving the eroneous readings. Thanks again for the insight!
