You are suppoed to make adjustments based on the temp of your thank. But the adjustments are real small, so I don't worry about it and calabrate to 7 and 10.

Trevor, I just got my new Pinpoint Controller and just calibrated it. I don't know if the monitor is exactly like to controller but your supposed to set the probe in the 7 first, make sure you let the numbers settle, adjust the calib pot until it reads 7.00. Then rinse the probe with roomtemp water then put it in the 10 ph solution and adjust the slope pot to read 10.00. Go back and forth between solutions and make sure they read 7 and 10 respectively! If your numbers swing too much it might be time for a new probe!
