Table
GSPNT X
X is the table entry (X = 0 through 9).
The values returned are:
Conductivity in µS/cm
Concentration in %
This table is designed to convert
conductivity measurements to
concentration. Up to 10 points.

pH
1-point pH Buffer
CALS1PB
Auto buffer recognition. Just initiate the command
and the system will adjust offset.
2-point pH Buffer
CALS2PB X
Where:
X = 0 is the first point
X = 1 is the second point
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.
1-point pH Sample
CALS1PS X
Where:
X = Desired number in pH
Sample calibration changes the current value
to a desired value.
Example: CALS1PS 7.5
2-point pH Sample
CALS2PS X Y
Where:
X = Point 0 or 1
Y = Desired Value in pH
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.
ORP
1-point ORP Sample
CALS1PS X
Where:
X = Desired number in mV
Sample calibration changes the current value to
a desired value. If the reading is cur235 mV
and the desired value is +300mV, then:
CALS1PS 300
Contacting
Conductivity
Adjust
Cell Constant
SCELL X
Where:
X = Desired cell constant
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.
