be used during calibration if you press Enter without inputting another value. Be sure not to
accept default values unless you have assured that they are correct. If no default value appears,
you must type a numerical value and press
Enter.
4.
After you input the calibration value, or accept the default, press Enter. A real-time display will
appear on the screen. Carefully observe the stabilization of the readings of the parameter that is
being calibrated. When the readings have been stable for approximately 30 seconds, press
Enter
to accept the calibration. The calibrated value is bolded on the example screen on the following
page.
5. Press
Enter to return to the Calibrate menu, and proceed to the next calibration.
CALIBRATION EXAMPLE
The example below for calibration of specific conductance, is designed to demonstrate the general calibration
protocol for all parameters. From the Calibrate menu, press
1-Conductivity and the following display will be
shown.
Select 1-SpCond (the generally-recommended method for calibration of a conductivity sensor), the following
prompt will appear which calls for your numerical input.
As noted above, the number in parentheses is the default value of this parameter and will be used in the
calibration if only
Enter is pressed without typing in another value. Similar prompts will be displayed during
the calibration of all parameters, but for some sensors, such as pH, no default values are provided. In these
cases, the user must input a numerical value and then press
Enter.
After the calibration value is input and Enter is pressed, a real-time display similar to the following will then
appear on the screen..
------------Cond calibration-----------
1-SpCond
2-Cond

Select option (0 for previous menu): 1
Enter SpCond in mS/cm (10):

To calibrate, press <Enter> when the readings are stable.

Note that all parameters that have been enabled will appear - not just the one being calibrated at the moment.
The user should carefully observe the stabilization of the readings of the parameter that is being calibrated
