4 Installation and commissioning
1. While unpacking check the electrode for
mechanicaldamage.Pleasereportanydamage
immediatelytoyourMETTLERTOLEDOsupplier.
2.Removetheprotectivecapandrinsetheelectrode
for a short time with deionized water. If the

5.ConnecttheelectrodeandthepHtransmitterwith
thecorrespondingcable(VP6,VP8,AK9).Observe
the connections scheme that accompanies the

please refer to instructions for the transmitter,
module and cable.
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 4.01
buffersolutions.Forfurtherdetailspleaseconsultthe
operatinginstructionsforthepHtransmitter.
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

3. If the electrode is stored in its armature the
advicesdescribedunderItem2apply,although
the electrolyte has to be slightly modied for
storagepurposes(2partsofbuffersolutionpH
9.2to10partsofelectrolyte)inordertoavoidany
corrosionofthearmatureparts.
4. If an electrode is inadvertently stored in a dry
conditionfor several days it must berinsedfor

agents can also be used. Protein contaminations on
the diaphragm can be removed with the cleaning
solution(orderno.51340070).
