Refilling Reference Electrode
The Reference Electrode cap needs to be removed prior to analysis and replaced
when the electrode is going to be stored. It is best practice not to let the tip of the
Reference Electrode dry out. To ensure this, always add a few drops of deionised
water into the cap before replacing on the electrode.
The Reference Electrode must contain
Reference Electrode Fill Solution
to
operate. Ensure the Reference Electrode is held vertically with the connector
upwards and determine that there is enough solution in the Reference Electrode.
Fill Solution at max
Fill solution level too low
The outer tube needs to be at least 1/3rd full. To top up the
Reference
Electrode Fill Solution
:
1. Place the reference electrode horizontal with the hole facing up
2. Slide the band down from the hole
3. Use the pipette to drop enough solution into the Reference Electrode to fill
it up.
4. Once topped up, replace the band to prevent the electrode fill solution
escaping.
Note: Only use the supplied Reference Electrode Fill Solution.
