The Wattson PH 035Z ref ord no 81374515 was delivered earlier this week. Wanted to calibrate and use today. When i switched it on it displayed 0.001 Put it into the 6,68 solution where it eventually changed first to 4,00 and then to 4,01 swirling all the time (while still in the 6.68 solution.) , it stayed on 4.01. Then rinsed with destilled water, dried and into the 4,01 solution, remained on 4.01 , tested nutrient tank (ph should read about 6) , remained on 4.0, tested municipal tap water 4,01 reading remained, should be about 6.8. rinsing and drying each time. I had one previously and it worked well. What is it with the little screwdriver. Is replacement probes available and and where is the calibration fluid. Plse advice. Rgds
