System Setup Section 3
Next highlight the Advanced setup selection, press Enter, and a display similar to the following
for specific conductance will appear.
You need to consider four options within this menu.
Is: Enabled. This determines whether or not the calibration of this parameter is enabled (allowed)
from the Run mode of the 6500 display. Highlight the selection “Is: Enabled”. Press Enter to
toggle back and forth between “Is: Enable” and “Is: Disabled”. Select the desired option.
Can override: Yes. This determines whether or not an error message can be overridden if it
occurs during the calibration procedure. Highlight the “Can override: Yes” selection. Press Enter
to toggle back and forth between “Can override: Yes” and “Can override: No”. Select the desired
option. Remember that a calibration error message usually implies a significant malfunction of
the 6-Series Sonde sensor that in turn indicates that service to that sensor is required if accurate
readings are to be obtained. Therefore, it is usually proper to select the “No” option with regard
to this selection. There are occasions when the user is aware that the error message is due to
special circumstances and thus the “Yes” option is appropriate, but these are rare.
Vari from Probe, Vari from Default or Fixed from Default. The software allows you to choose
only one of these three choices. During setup choose “Vari from Probe”. This is the default
parameter value that appears on the 6500 display when the calibration procedure is initiated.
With this selection, the current reading of the parameter will be displayed on calibration startup
and this value can be varied from the 6500 keyboard to reflect the true value. For more detailed
information on these choices, see Appendix F, Advanced Calibration Setup.
Default = 1000. The value of the default calibration value for this parameter is only needed if
you choose one of the default choices above. If you choose “Vari from Probe”, you need not set
a value here.
A calibration setup display for each activated parameter, except temperature that requires no
periodic calibration, is accessible after the Advanced setup selection is made from the Calibrate
setup menu. To view other parameters, use the right and left arrow keys to scroll horizontally
between parameters using the scroll bar at the bottom of the screen (see screen above). Use the
descriptions above to set each of the 4 options for these other parameters.
After configuring your sensor calibrations as described above, press Esc to return to the Main
menu.
