X is the table entry (X = 0 through 9).
The values returned are:
Conductivity in µS/cm
Concentration in %

CALS1PB
CALS2PB X
Where:
X = 0 is the first point
X = 1 is the second point
CALS1PS X
Where:
X = Desired number in pH
CALS2PS X Y
Where:
X = Point 0 or 1
Y = Desired Value in pH
CALS1PS X
Where:
X = Desired number in mV
SCELL X
Where:
X = Desired cell constant
Comments
This table is designed to convert
conductivity measurements to
concentration. Up to 10 points.
Comments
Auto buffer recognition. Just initiate the command
and the system will adjust offset.
Auto buffer recognition.
CALS2PB 0 stores calibration data from the first
buffer solution.
CALS2PB 1 stores calibration data for the second
buffer solution.
Readings do not change until the second point
has been accepted.
Sample calibration changes the current value
to a desired value.
Example: CALS1PS 7.5
Put the sensor in the first sample solution and adjust
the first point to the desired reading:
Example: CALS2PS 0 7.5
Put the sensor in the second sample solution and
adjust the second point to the desired reading:
Example: CALS2PS 1 4.12
Readings do not change until the second point
has been accepted.
Sample calibration changes the current value to
a desired value. If the reading is currently +235 mV
and the desired value is +300mV, then:
CALS1PS 300
Make a user guide adjustment to the actual
cell constant. This will change the calibration.
Example: SCELL 1.0045
This will change the cell constant and change
the measurement.
