reading.
e. Press once to confirm new value and end the
calibration sequence for this particular solution type. If another
solution type is also to be measured, change solution type now
and repeat this procedure.
2. Reloading Factory Calibration
(Cond, MIN/SALT or TDS)
If calibration is suspect or known to be incorrect, and no standard
solution is available, the calibration value can be replaced with the
original factory value for that solution. This “FAC” value is the same
for all P

, and returns you to a known state without solution in
the cell. The “FAC” internal electronics calibration (which bypasses
the electrodes and cell) is not intended to replace calibration with
conductivity standard solutions. If another solution type requires resetting,
change solution type and repeat this procedure.

c. Press key until “FAC” appears and release.
d. Press to accept the factory calibration setting.
3. pH Calibration
Important: Always “zero” your P

with a pH 7 buffer solution
before adjusting the gain with acid or base buffers, i.e., 4 and/or 10.
a. pH Zero Calibration
1. Rinse sensor well 3 times with 7 buffer solution.
2. Refill both sensor wells with 7 buffer solution.
