Select this screen to display the following:
Select “SETUP KNOWN SONDES” and then indicate the
address of the sonde you want to setup. A screen containing the
sonde model and number of data values will appear briefly. Then
you will be asked to verify, parameter by parameter, what data
you want to store. The screens will look similar to the one below:
Indicate if you want to store the data for that particular
parameter and then advance through the rest of the parameter
screens. Once you have defined your data storage options, select
“DONE.”
You will be prompted that you have entered a new hardware
setup and asked if you want to erase the stored data. Indicate
“YES” or “NO.” A partition memory status message will be dis-
played and (if a parameter exists that can be calibrated) you will
then advance to the calibration screen (refer to “SONDE CALI-
BRATION AND VALIDATION” on this page). If you do not want
to calibrate or validate, select “DONE” to return to the Hardware
Options screens.
6.6 Sonde Calibration and
Validation
It is recommended that calibration of your sonde be done
in the lab, according to manufacturer’s recommendations.
However, for your convenience, the 6712 allows for field cali-
bration of pH, Dissolved Oxygen (DO), and Oxidation Reduction
Potential (ORP).
Field calibrations are stored in the sampler, NOT the sonde, and
are used to modify readings from the sonde until a new sonde is
connected. When a sonde is moved to another sampler, it will
retain calibration constants set in the lab, but will not retain any
that were set in the field.
Although field calibration is limited to three parameters, you can
validate any of the available parameters. Validation allows you
to immerse the sonde in a known solution, note the readings, and
see if the sonde is functioning properly. The validation process
does not modify any readings like calibration does; it merely
alerts you to inaccurate ones.
No data will be stored, nor will enable conditions be updated,
while calibrations or validations are being performed.
