rapid scrolling of the 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.
