Sensor Data Filter
GSFIL
Filter time constant from 0 to 100 seconds.
Integers only.
The sensor process variable will reach
90% of the final value in “X” seconds.
Temperature Data
Filter
GTFIL
Filter time constant from 0 to 100 seconds.
Integers only.
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.
Buffer Set for pH
Calibration
GPHBUF
Buffer type set for auto recognition during
buffer calibration.
0 = 4,7, 10 pH Buffer
1 = DIN Buffer Type
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

Table
GUPNT 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.
