Hello,
I purchased a Pinpoint pH Monitor from your website and am trying to calibrate it. I followed the instructions but ran into some trouble when I tried to adjust the 4 10 dial. The monitor was unresponsive so I let it sit for a couple minutes in the solution however it still did not adjust. Have I made an error or is the device faulty?
