Electrode Replacement; Specifications - Extech Instruments ExStik CL200 User Manual

Cleaning and Maintaining the Electrode
The chlorine electrode arrives in factory-cleaned condition and is ready for use. The electrode will
perform best after 2 or 3 tests. Before and after testing, firmly wipe the electrode tip with a clean, dry
towel to remove accumulating compounds. When not in use, the CL200 should be stored with the
electrode cap in place.

Electrode Replacement

The CL200 is shipped with an electrode attached. If the electrode must be replaced, or if a pH or
ORP electrode is to be installed, perform these steps:
1. Swtich OFF the unit.
2. To remove an electrode, unscrew and remove the electrode collar (turning the collar counter-
clockwise).
3. Gently rock the electrode from side to side, pulling it downwards, until it disconnects from the
meter.
4. To attach an electrode, allign the slots and carefully plug the electrode into the meter socket.
5. Tighten the electrode collar firmly enough to make a good seal (a rubber gasket seals the
electrode with the meter).
