l
Additional text 1/2
On Main screen, Additional text helps you identify each measurement. However, Hold or Wash
Display are prioritized. When Hold or Wash is being displayed, additional text is not displayed.
Additional text can display up to 12 characters.
l
Conductivity Unit
Select whether to convert automatically or fix the conductivity subunit.
Select /cm or /m in sensor setting.
Conductivity Unit: Auto, nS, µS, mS, S, kS
l
TB/CL Decimals on screen
You can specify the maximum number of display digits below the decimal point for turbidity and
residual chlorine.
For example, if you specify 1-digit, displayed value is rounded to the nearest one decimal place.
However, since the total number of digits after the integer part and the decimal point is four, even
if “3 digits” is specified, only the second digit of the decimal point is displayed, when the number
of digits of the integer is 2 digits. You cannot specify the digits for temperature, pH or conductivity.
4.5.2 Trend
On Trend screen, determine the sensors and process parameters you want to display for each
trend. 1st to 8th trend can be set.
l
X-axis: Timing
Select the settable scale from the list.
l
Low/High
Set Y-axis primary value scale i.e. Maximum or Minimum value for each trend screen.
[Process parameter slot]
Select sensor for trend from “Sensor 1-1”, “Sensor2-1”, “Sensor 2-2”, “Converter”. Don’t select
“Sensor 2-2”.
If you need to set converter parameters as process parameters (mA input), set “Converter”.
You need to register MODBUS address to the sensors in advance. Read 4.6 Advanced
settings.
Process parameters you can select to output are as follows:
TB: Turbidity
FC: Residual Chlorine Concentration, Temperature
PH: pH, Temperature
SC: Conductivity, Temperature
Converter: AI
Set process parameter to output according to sensors. If the setting is not configured properly,
the trend fails to be displayed correctly.
NOTE
Updating the trend screen setup resets the current trend graph and starts a new one.
