1. Remove the battery cover by placing your
thumb on the indented portion on the rear
of the battery cover and gently pressing in
an upward motion.
2. Insert the new 1/2AA Li-Thionyl Chloride
battery in the slot at the top of the unit.
When looking at the front of the unit the
positive terminal of the battery should be
on the left. See internal guide symbols.
3. Now turn the clip 90 degrees to the right so it clicks
over the electrode body. Adjust the height of the clip to
suit the size of your container. The clip can be used to
attach the unit onto most small beakers and the storage
stand. Ensure you have sufficient volume in your beaker
to balance the unit.
2. Turn the clip attached to the temperature sensor to the
left by 90 degrees. Carefully align and screw the pH
electrode into the large socket on the base of the unit.
Ensure that the electrode is straight and screw gently into
the unit. Do not force the electrode as this may damage
the thread. Tighten so that the seal is compressed.
1. Hold the white cap and unscrew the electrode soaker
bottle. Move white lid up electrode, pull rubber seal down
over electrode tip, then remove lid.
3. Replace the battery cover by engaging the
front clips and then pressing the rear clips into
position with a light pressure on the indented
portion of the cover.
NOTE: The battery will not work if inserted
the wrong way round. Alternative 3.6V cells
can be used but may affect performance
