4. Replace the battery carrier, reattach the battery compartment cap and tighten securely
Electrode Replacement
1. To remove the electrode, first turn the instrument OFF and then unscrew and remove the
electrode retaining collar. (turn the collar counter-clockwise to remove)

housing and then carefully push the electrode into the meter socket until it is fully seated
4. Tighten the electrode retaining collar firmly enough to seal the electrode with the meter
Electrode Storage

minutes of soaking in a fluoride solution before the specified performance can be achieved.
The instrument will give an error code when the electrode can no longer be calibrated
