Electrode Replacement
1. To remove an electrode, unscrew and completely remove the electrode collar (turn the collar
counter-clockwise to remove).
2. Gently rock the electrode from side to side, pulling it downwards, until it disconnects from the
meter.
3. To attach an electrode, carefully plug the electrode into the meter socket (note that the
electrode connector is keyed, ensuring proper connection).
4. Tighten the electrode collar firmly enough to make a good seal (a rubber gasket seals the
electrode with the meter).
