I cannot say for sure without looking at you pH meter and probe, but the most likely problem is that you pH probe is broken or clogged. It probably needs to be replaced.

Missing parts and bad probe? Can you send it back?

That's what I was thinking, a bum probe. If you bought it new, send it back. If you bought it used, you can get a probe from aquariumplants.com for about $40. I'm sure you can find one cheaper than that if you try.

Calibrate to the 7.01 solution only..... I believe it says that as well on the instructions...........
Don't mess with the back of the controller.......

A calibration with 1 point isn't a calibration at all, and the manual says to calibrate to 4 and 7.
