• Byusingtheadditionalconcentrationtable
The additional concentration table indicates the relation between the conductivity and the
concentration at the reference temperature. Set the “Additional table” to “Enabled”. The
concentration can be obtained from the additional concentration table.
 Afterenteringvalues,select“Yes”for“Checkvalues?”.Valuesareinterpolatedintoempty
cells. If any mandatory cells are left blank, an error will be issued. An error message is also
issued if there is any error in the concentration table.
After completing entering values in the additional concentration table, set “Additional table”
to “Enabled”.
l Unit for table
Select the concentration display units from among %, ppt, ppm, and ppb.
Changing the unit will not result in a re-calculation of the table. Reenter values in the additional
concentration table.
7.1.7 Sensor diagnostic settings
This screen is used to set items relating to sensor diagnostics displayed on the screens invoked
by pressing
.
Gauges are displayed for only parameters that have been enabled in “Sensor diag. settings.”
ParameterssettoDisableareprovidedwithabardisplay.
ThesettingparametersincludeProgresstimeandHeatcycle.Itisalsopossibletosetthe“Bad
limits” of the progress time and heat cycle and the “Heat cycle temp” and “Heat cycle time” of the
heat cycle.

Process parameter
Available process parameters depend on the selected “Measurement” item in Measurement
setup. Refer to Table 7.2.
