2.0 Preparing Bluelab Combo Meter for Use
Preparing the Bluelab Combo Meter for use involves hydrating the pH probe,
inserting 2 x AAA batteries, connecting the pH probe and calibrating the pH.
These tasks are performed before the meter is used for the first time.
1
Hydrate pH Probe
Remove pH probe tip protective cap. Soak tip in fresh water for at least one hour.
Soaking tip for 24 hours will improve the probe's activity and is recommended if the
probe tip has been allowed to dry.
CAUTION: Do not use de-ionized or distilled water. When probe is not in use, put
some fresh water into the protective cap and place back onto probe.
2
Insert Batteries
Open battery compartment by sliding back cover
down and insert 2 x AAA batteries.
CAUTION: Rechargeable batteries are not used
as they will cause problems.

quarter turn.
