Where the DataStick replies with a number
that means...
PH:
0 = pH units
1 = mV units
ORP:
0 = mV
Conductivity:
0 = µS/cm
1 = %
2 = TDS
3 = MΩ•cm
DO/Ozone:
0 = ppm
1 = %
0 = ˚C
1 = ˚F
Filter time constant from 0 to 100 seconds.
Integers only.
Filter time constant from 0 to 100 seconds.
Integers only.
Buffer type set for auto recognition during
buffer calibration.
0 = 4,7, 10 pH Buffer
1 = DIN Buffer Type
Salinity setting between:
0 and 999.9 mS/cm
Pressure setting between:
539.2 to 792.4 mmHg
Conductivity reference temperature is set
from:
0˚C to 100˚C
Conductivity slope is set from:
0 to 9.9%/˚C
X is the table entry (X = 0 through 9).
The values returned are:
Conductivity in µS/cm
Concentration in %
Comments
As different sensor heads are added to
the family of DataStick measurements
this list will be expanded.
The sensor process variable will reach
90% of the final value in "X" seconds.
The temperature variable will reach
90% of the final value in "X" seconds.
Caution: It is advised to keep the
temperature and process filter
constants equal.
pH buffer calibration: the current
reading will be changed to the closest
value in the buffer set selected.
DIN Buffer Standards are:
1.09, 4.65, 6.79, 9.23 and 12.75 pH
Average salinity for compensation
of dissolved oxygen measurement.
Average pressure for compensation
of dissolved oxygen measurement.
Default value is 25˚C
Default is 2.0%/˚C
This table is designed to convert
conductivity measurements to
concentration. Up to 10 points.
