conductivity cell being careful not to
touch the tip to the existing solution.
Depress the top of the pipette to the
SECOND STOP (all the way down)
being careful to keep the tip over the
cell. Release the plunger button and let
it return to the REST position.
2. T-Plunger Instructions
To PLUNgE the cell:
With the cell extender installed and
solution in the cell, insert the tip of the
T-plunger in the cell extender until the
arms of the T-plunger are flush against
the rim of the cell extender. Solution will
overflow the cell.
Keeping the arms of the T-plunger flush
against the rim of the cell extender, rotate
the T-plunger from side to side, allowing
the arms of the T-plunger to slide along
the rim of the cell extender.
Remove the T-plunger from the cell by
lifting it straight up out of the cell, being
careful to keep it centered over the
mouth of the cell extender. When the
T-plunger is completely out of solution,
tap the T-plunger once firmly on the rim
of the cell extender to dispel any clinging
solution back into the cell.
Remove the T-plunger completely from
the cell area.
3. Mixing Solution in Cell
a. Agitate
When the display says to agitate (“agit”): grasp
the instrument on both sides of the keypad (keypad
facing up) with your hands so you don’t accidentally
drop or release it. Agitate the solution in the cell by
swinging the cell cup area of the unit up and down 3
times. Do NOT shake the instrument vigorously as
this could create bubbles in the sample solution.
b. Hold
When the display says to hold (“hOld”):
Hold the instrument steady in the horizontal position
while the instrument records a measurement.
Insert the T-plunger all the way
down into the cell extender then
rotate it from side to side.
Hold the T-plunger over the cell
then tap firmly so that solution is
dispelled back into the cell cup.
“agit”: When “agit”
displays, swing the
cell end of the 9P up
and down 3 times.
