- Clean and rinse the electrodes thoroughly. 
- Prepare the electrodes properly. 
- 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.
 
 
Standards and Reagents 
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 or deionized water, or a simple mathematical miscalculation. 
 
Sample 
Look for possible interference, 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 HintsSample Requirements
, and
 
Interference
.) 
 
Technique 
Be sure that the electrode's limit of detection has not been exceeded and the analysis method is 
clearly understood and is compatible with the sample. 
 
Refer to the instruction manual again. Reread the sections

  and 
ELECTRODE CHARACTERISTICS.
