5 Operation: Calibration of the electrode
and pH transmitter
Before a calibration immerse the electrode for
10minutesinapH7.00orpH4.01buffersolution
whilst connected it to the transmitter. A 2-point
calibration is recommended, e.g. pH 7.00 and pH
4.01buffersolutions.Forfurtherdetailspleaseconsult
theoperatinginstructionsforthepHtransmitter.
6 Maintenance
1. After each working cycle the electrode tip and
diaphragm have to be carefully rinsed with
deionized water. Any remaning of the solution
