Smoothing Factor
Increase the smoothing factor percentage to dampen the response to changes. For
example, with a 10% smoothing factor, the next reading shown will consist of an
average of 10% of the previous value and 90% of the current value.
Default Temp
If the temperature signal is lost at any time, then the controller will use the Default
Temp setting for temperature compensation.
Installation Factor
Do not change unless instructed by the factory.
Cable Length
The controller automatically compensates for errors in the reading caused by varying
the length of the cable.
Gauge
The cable length compensation depends upon the gauge of wire used to extend the cable
Cell Constant
Do not change unless instructed by the factory. The Walchem sensor is 6.286. Sensors
made by others are not supported.
Range
Select the range of conductivity that best matches the conditions the sensor will see.
Temp Compensation
Select between the standard NaCl temperature compensation method or a linear %/
degree C method.
Temp Comp Factor
This menu only appears if Linear Temp Comp is selected. Change the %/degree C to
match the chemistry being measured. Standard water is 2%.
Units
Select the units of measure for the conductivity.
Name
The name used to identify the sensor may be changed.
Type
Select the type of sensor to be connected.
5.2.3 Temperature
Settings
Touch the Settings icon to view or change the settings related to the sensor.
Alarms
Low-Low, Low, High and High-High Alarms limits may be set.
Deadband
This is the Alarm Deadband. For example, if the High Alarm is 100, and the dead-
band is 1, the alarm will activate at 100 and deactivate at 99.
Reset Calibration Values
Enter this menu to reset the sensor calibration back to factory defaults.
Cal Required Alarm
To get an alarm message as a reminder to calibrate the sensor on a regular schedule,
enter the number of days between calibrations. Set it to 0 if no reminders are necessary.
Alarm Suppression
If any of the relays or digital inputs are selected, any alarms related to this input will
be suppressed if the selected relay or digital input is active. Typically this is used to
prevent alarms if there is no sample flow past the flow switch digital input.
Smoothing Factor
Increase the smoothing factor percentage to dampen the response to changes. For
example, with a 10% smoothing factor, the next reading shown will consist of an
average of 10% of the previous value and 90% of the current value.
Name
The name used to identify the sensor may be changed.
Element
Select the specific type of temperature sensor to be connected.
5.2.4 pH
Settings
Touch the Settings icon to view or change the settings related to the sensor.
Alarms
Low-Low, Low, High and High-High Alarms limits may be set.
Deadband
This is the Alarm Deadband. For example, if the High Alarm is 9.50, and the dead-
band is 0.05, the alarm will activate at 9.51 and deactivate at 9.45.
Alarm Suppression
If any of the relays or digital inputs are selected, any alarms related to this input
will be suppressed if the selected relay or digital input is active. Typically this is
used to prevent alarms if there is no sample flow past the flow switch digital input.
