ELECTRODE CONDITIONING

& MAINTENANCE

PREPARATION PROCEDURE
Remove the protective cap.
DO NOT BE ALARMED IF ANY SALT DEPOSITS ARE PRESENT.
This is normal with electrodes and they will disappear when rinsed
with water.
During transport tiny bubbles of air may have formed 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

HI 70300

storage solution for at least one hour.

Note: When the HI 8615 and HI 8615L are used in conjunction

with the Hanna new

HI 8512 indicator or HI 8720 controller,

the calibration can also be performed on the indicator/
controller. In this case slight adjustment can be made on the
indicator/controller even if the whole system calibration is
advised, always starting from the transmitter.
