Operation
5.5 The commands under SENSOR SETUP
SENSOR SETUP
SELECT SENSOR (for several sensors)
CALIBRATE
1 POINT BUFFER
Calibration using a buffer — normally pH 7, see 5.6.1 Calibration using
a buffer solution .
2 POINT BUFFER
Calibration using two buffers — normally pH 7 and pH 4 or 10, see
5.6.2 Calibration using two buffer solutions .
1 POINT SAMPLE
Calibration using a known sample, see 5.6.3 Calibration using a
sample solution .
2 POINT SAMPLE
Calibration using two samples, both with known pH value, see 5.6.4
Calibration using two sample solutions .
PROCESS TEMP Set temperature displayed.
CAL CONFIG
OUTPUT MODE
Choose between:
ACTIVE, measured value and thus the outputs signals follow
the calibration process;
HOLD, the last measured value and thus the output signal
are frozen;
TRANSFER, the measured value and thus the output signal are set
to a defined value and
CHOICE, after each calibration you can choose one of the three above
options.
CAL REMINDER
You can set when the next calibration is to be performed. The
controller then automatically indicates when the next calibration is due.
DEFAULT SETUP Return to the factory settings after prompt for confirmation.
