Improving Response Time
If the response time or reproducibility is decreasing, follow the steps below to improve response
time.
1. Remove then reinstall the rubber stopper. Do not close the stopper; the stopper should remain
open during operation and closed when in storage.
2. Confirm that the inner solution exudes from the opening.
3. Repeat steps 1 and 2 several times. If performance does not improve, do one of the following,
as appropriate:
• Remove dirt: wipe off with a soft cloth soaked with a neutral detergent.
• Remove oil residue: wipe off with a soft cloth soaked with an appropriate organic solvent,
such as acetone or alcohol.
• Remove inorganic substances: rinse with approximately lN HCl. Do not immerse the elec-
trode in a concentrated acid for a long time.
