  • Page 85 If the internal buffer is pH 7, then a calibration buffer of pH 7 should yield a signal around 0 mV. Deviations of less than 1 pH (approx. 60mV) are tolerated. Dr. A. Kuntze Gutes Wasser mit System Robert-Bosch-Str. 7a...
  • Page 86 If the sensor still looks normal, it is worth the trouble to empty and refill it with fresh 3M KCl solution. Wait 24h and then check the zeropoint again. Dr. A. Kuntze Gutes Wasser mit System Robert-Bosch-Str. 7a...

  • Page 90 As with the measuring input, a defective cable or sensor can be the cause for this message. You can check temperature sensors with an Ohmmeter – a Pt100 has a resistance of approx. 109 Ohm at room temperature, a Pt1000 approx 1080 Ohm. Dr. A.
