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accumulation.

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housingasdescribed

intheinstructionsforthehousing.

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.

“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housing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housing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.

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.
