Hi, I have a calibration issue with my TVIRD ph Meter. The users manual tells I have to push the CAL button for 5 seconds, then immerse the electrode into the 6.86 solution, then wait while 6.86 flashes 3 times. However, my ph meter randomly flashes 4.00 or 6.86 in these cases. Also, I tried to push again quicly the CAL button after the 5 seconds once or twice to change calibration mode to 4.00 or 9.18, as it is described in the users manual, but nothing happens. It flahses always 4.00... Please help what is wrong. Regards, Zsolt
