ELECTRODE PREPARATION
PREPARATION PROCEDURE
Remove the electrode protective cap.
DO NOT BE ALARMED IF ANY SALT DEPOSITS ARE PRESENT. This is normal with electrodes and
they will disappear when rinsed with distilled/deionized 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 is dry, soak the electrode in
HI 70300
Storage Solution for at least one hour.
This screen is displayed when the instrument is in
titration mode. Press the
Start
to begin a titration,
Meter
to enter ORP meter mode or
Prime
to enter
into the prime function.
TITRATION MESSAGES
The titration result, expressed as the concentration of
sulfur dioxide in ppm (mg/L), is displayed
automatically at the end of the titration. Press the
Restart
to start another titration or
ESC
to return to
the main screen.
This error message appears when the input reading
(
±
2000 mV) exceeds the input limits during a
titration.
This screen appears when the sample concentration
is out of range.
