Maintenance
Battery Replacement
1.
Twist off the battery compartment cover.
2. Holding the battery housing in place with a fi nger, pull out the battery
carrier using the two small tabs.
3. Replace the four (4) CR2032 batteries observing proper polarity.
4. Replace the battery carrier, reattach the battery compartment cap and
tighten securely.
Electrode Replacement
1.
To remove the electrode, fi rst turn the instrument OFF and then unscrew
and remove the electrode retaining collar. (Turn the collar counter-clock-
wise to remove).
2. Gently rock the electrode from side to side, pulling it away from the
meter until it disconnects.
3. To attach an electrode, align the positioning “keys” on the electrode and
the main body housing and then carefully push the electrode into the
meter socket until it is fully seated. CAUTION: Take care to align pins
carefully. Bent or broken pins will cause the meter to malfunction.
4. Tighten the electrode retaining collar fi rmly enough to seal the electrode
with the meter.
Electrode Storage
1.
The module and can be stored wet or dry. If stored dry it will be neces-
sary to allow approximately 15 minutes of soaking in a fl uoride solution
before the specifi ed performance can be achieved. It is recommended that
the electrode be stored wet in the last test solution used by the instrument
(fl uoride ion plus TISAB reagent).
2. The instrument will give an error code when the electrode can no longer
be calibrated.
3. If the instrument will not calibrate, clean the fl uoride electrode surface
and recalibrate the instrument. If the meter still does not calibrate, replace
the electrode.
