Getting Started
• Remove the cap from the bottom of the ExStik
TM
to expose the electrode bulb and
reference junction
• Before first use or after storage, soak the electrode (with its cap removed) in a pH 4
solution for about 10 minutes (PH100 only)
• White KCL crystals may be present in the cap. These crystals will dissolve in the soak or
they can be simply rinsed with tap water
• Always calibrate close to the expected measurement value
• Twist off the battery compartment cap to access the battery tab; remove this plastic tab
before first use
• To preserve Electrode life keep the sponge in the protective cap soaked with a pH 4
solution (PH100), deionized, distilled water (RE300) when not in use (store vertically)
