4 Installation and commissioning

1. While unpacking check the electrode for

mechanicaldamage.Pleasereportanydamage

immediatelytoyourMETTLERTOLEDOsupplier.

2.Removetheprotectivecapandrinsetheelectrode

for a short time with deionized water. If the

electrodehasalreadybeenusedthesensitivepart

canbecleanedwithasofttoothbrushandamild

soapsolution,andthenrinsedforashorttimewith

deionizedwater.Afterrinsingtheelectrodeshould

onlybedabbed.AnyrubbingofthepHsensitive

glasscanincreasetheresponsetimeasaresult

ofelectrostaticcharge.

3.Check thespace behind the pH sensitive glass

forairbubblesandremoveanyairbubblesthat

maybepresentbyshakingtheelectrodeslightlyin

a vertical direction.

4.Placetheelectrodeintothearmatureasdescribed

intheinstructionsforthearmature.

5.ConnecttheelectrodeandthepHtransmitterwith

thecorrespondingcable(VP6,VP8,AK9).Observe

the connections scheme that accompanies the

cableorthetransmitter.

6. Intelligent ISM

®

sensorssuchasInPro480X(ISM)

and InPro 48XX i enable “Plug and Measure”

and expanded diagnostics. For installation,

commissioningandoperationoftheISMsystem

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

10minutesinapH7.00orpH4.01buffersolution

whilst connected it to the transmitter. A 2-point

calibration is recommended, e.g. pH 7.00 and pH 4.01

buffersolutions.Forfurtherdetailspleaseconsultthe

operatinginstructionsforthepHtransmitter.

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

beingmeasuredonthesepartsmustbeavoided

at all costs!

2. Iftheelectrodeisnotinuseithastobestoredwith

theelectrodetipandthediaphragmimmersedin

atankofelectrolyte(9823/3MKClorFriscolyt™

9848).).

3. If the electrode is stored in its armature the

advicesdescribedunderItem2apply,although

the electrolyte has to be slightly modied for

storagepurposes(2partsofbuffersolutionpH

9.2to10partsofelectrolyte)inordertoavoidany

corrosionofthearmatureparts.

4. If an electrode is inadvertently stored in a dry

conditionfor several days it must berinsedfor

severalhoursinastandardstorageelectrolyte.

5. Theplug-inheadshouldoccasionallybechecked

forpossibletracesofmoisture.Ifnecessaryclean

itthoroughlywithdeionizedwateroralcoholand

thendryitoffcarefully.

7 Removal of sources of malfunction

Withasofttoothbrushandwateranyresiduescan

easilyberemovedfromtheelectrode.Mildwashing

agents can also be used. Protein contaminations on

the diaphragm can be removed with the cleaning

solution(orderno.51340070).

Warning: Solutionscontaininghydrouoridesdamage

thepHsensitivepartoftheelectrode.

8 Disposal

Itistheuser’sresponsibilitytodisposeofthesensor

ina professional manner. The sensorcan contain

electroniccomponentsthatrequiredisposalsuchthat

nopersonsortheenvironmentareendangered.

9 Guarantee

Onmanufacturingdefects12monthsafterdelivery.

10 Storage conditions

Werecommendthattheelectrodesarestoredatroom

temperature.
