Negative, High, or Erratic Measurements
Many of the previous steps in this chapter will help troubleshoot negative or erratic measurements. If the
previous steps did not remedy the situation, you may need to perform one of the following procedures.
Conductivity Autozero
If the Analyzer is returning unusually high IC or conductivity values, a sample conductivity cell autozero may be
necessary. If you have recently run a system protocol, let the Analyzer run for at least five hours before
performing a conductivity autozero.
1. Make sure the Analyzer is not taking measurements.
2. Press the
Menu
button and select the
Maintenance
tab.
3. Press the
Advanced
button.
4. Press the
Cond. Autozero
button.
Sample Conductivity Cell Calibration
If for any reason the sample conductivity cell has been replaced, or you suspect poor performance of the cell,
then you may need to perform a sample conductivity cell calibration. For this protocol you will need a Sievers 25
µS/cm Conductivity Standard (as HCl). If you have a Super
iOS
, place this standard in vial port 1.
1. Make sure the Analyzer is not taking measurements.
2. Press the
Menu
button and select the
Maintenance
tab.
3. Press the
Cal/Ver/Validate
button.
4. Press the
Sample Cell Cal
button.
