- Use the proper filling solution. 
- Adjust the pH and the ionic strength of the solution by the use of the proper ISA. 
- Measure correctly and accurately. 
- Review 

TROUBLESHOOTING HINTS. 

Whenever problems arise with the measuring procedure that has been used successfully in the past, 
be sure to check the standard and reagent solutions.  If in doubt about the credibility of any of the 
solutions, prepare them again.  Errors may result from contamination of the ISA, incorrect dilution 
of standards, poor quality distilled/deionized water, or a simple mathematical miscalculation. 
 

Look for possible interferences, complexing agents, or substances which could affect the response 
or physically damage the sensing electrode (or the reference electrode) if the electrodes work 
perfectly in the standard, but not in the sample. 
 
Try to determine the composition of the samples prior to testing to eliminate a problem before it 
starts.  (See 

Measuring Hints, Sample Requirements,

 and

 Interferences

.) 

Be sure that the electrode's limit of detection has not been exceeded. Be sure that the analysis 
method is clearly understood and is compatible with the sample. 
 
Refer to the instruction manual again. Reread sections on 

GENERAL PREPARATION and 

ELECTRODE CHARACTERISTICS.
