ELECTRODE CONDITIONING
AND MAINTENANCE
PREPARATION
Remove the protective cap.
DO NOT BE ALARMED IF ANY SALT DE-
POSITS ARE PRESENT.
This is normal with electrodes and they will
disappear when rinsed with water.
During transport tiny bubbles of air may form
inside the glass bulb. The electrode cannot
function properly under these conditions. These
bubbles can be removed by "shaking down"
the electrode as you would do with a glass
thermometer.
If the bulb and/or junction are dry, soak the
electrode in HI70300 or HI80300 Storage
Solution for at least one hour.
