duringoperation,andre-adjustifrequired.

2. Regularly check the electrolyte level in the sensor.

Whenreachingtheendofthebulbousshaftsection

(reservoir),rell with the electrolyteindicated on the

chamber (red marking) is then lled to a level ap

-

proximately0.5to1.0cmhigherthanthatoftheouter

chamber.

4. Carefullyrinsethesensortip anddiaphragm(s)with

deionizedwateraftereachproductioncycle.Underno

circumstancesmustmeasuringsolutionbeallowedto

7. Ifasensorisstoreddryforafewdaysbymistake,letit

soakinthenormalstorageelectrolyteforseveralhours

before use.

8. Occasionallychecktheconnectorforpossibletracesof

moisture.Ifnecessary,cleanwellwithdeionizedwater

oralcohol,andafterwardsdrycarefully.

7 Trouble-shooting

Atsluggishresponsetime(e.g.afteralonganddrystor-

ageperiod),reactivationofthepHsensitiveglassmaybe

necessary.DipthepHsensitiveglass(butnofurthersen

toremovesuchprecipitation.Atrepeatedproblemsofthis

type,considerswitchingtosensorswithFriscolyt™/9848
