11.4 CALIBRATION MODE
In CALIBRATION OPEN MODE the unit collects data and outputs all raw data
and processes measurements allowing a user to calculate operational constants.
To enter the CALIBRATION MODE the “***C” command sent from the OPEN
MODE (See Open Mode Above). After entering CALIBRATION MODE the unit
will send the following frame of data when polled using a carriage return or line
feed. The SET CONTINUOUS “SC” command also operates in Calibration Mode
***C
-9433, 639606, -8351, 491805, 2.2, 21.0, 2.1
Where:
-9433 = Counts Electronic Zero Reference
639606 = Counts Electronic Full Scale Reference
-8351 = Counts Conductivity Circuit Reference
491805 = Counts Temperature Circuit
2.2
= Calculated Conductivity pS/M
21.0
= Calculated Temperature Celsius
2.1 = Calculated Compensated Conductivity pS/M
