• Check that electrode is in correct
standard.
• Recalibrate using fresh standards
• Check that the appropriate cell constant
is entered in the method setup.
• Clean electrode
• Replatinize conductivity cell (if
applicable)

Conductivity
Calibration
Standard Error
Yes
The conductance
being measured
is the same for
two different
standards.
• Check that the two different standards
are being used and that the electrode is
in the correct standard.
• Make fresh standards and repeat the
calibration.

Cell Constant
Yes
The cell constant
is not in the
range of 0.001 to
199.0
• Repeat calibration using fresh

• Repeat calibration
• On Air calibration make sure sponge in
calibration sleeve is damp.
• On water calibration make sure water
is saturated with air by bubbling but
stirred to prevent keep bubbles off the
membrane surface.
• Polish the cathode and replace the
membrane cap and fill solution.
