1. Remove protective cover from HI 4010 sensor tip.
2. Due to shipping or storage the internal solution inside
the electrode may have developed an air pocket near
the membrane. Gently shaking the sensor down (like
the old style mercury thermometer) will place the in-
ternal solution next to the membrane. Note: when the
sensor is inverted an air pocket will be seen which is
normal.
3. Prepare HI 5315 reference electrode by filling outer
electrolyte reservoir with HI 7075.
4. Place sensor and reference electrodes into electrode
holder and connect cable connectors to meter.
HI 4110
1. Unwrap plastic film seal found over ceramic junction
on inner stem and discard. This is only used for ship-
ping and long term storage.
2. Open the glass vial that contains the fluoride module
(HI 4110-51) and remove from container.
3. Ensure the o-ring is installed on module before screw-
ing into inner stem. Do not over tighten.
4. Due to shipping or storage the internal solution inside
the module may have developed an air pocket near
the membrane. Gently shaking the sensor down (like
the old style mercury thermometer) will place the in-
ternal solution next to the membrane. Note: When
inverted, an air pocket will be visible inside the sensor
which is normal.
5. Rinse inner stem with deionized water making certain
to wet the o-ring found on the inner stem.
