Deadband
This is the Alarm Deadband. For example, if the High Alarm is 3 g/l, and the dead-
band is 0.10, the alarm will activate at 3.01 g/l and deactivate at 2.90 g/l.
Calibration Offset
This menu is used to change the sensor reading without performing a water/sample
calibration. This calibration is best performed at normal operating temperature.
Keep the immersible sensor in place or have solution flowing through the flow-
through sensor. Take a sample of the solution and note the concentration displayed
by the controller. Carefully perform the normal laboratory analysis of the metal
concentration. Calculate the offset by subtracting the displayed value from the lab
results. If the lab analysis is significantly different, adjust the offset
using the arrow keys to change the value and the +/- sign. If the controller’s display
is higher than the lab analysis, the offset should be negative.
The maximum offset for calibration offset is 10 g/l or oz/gal from the last water/
sample calibration value. If you have an offset larger than this, then perform a new
water/sample calibration (see section 5.2).
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 neces-
sary.
Alarm & Datalog
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. At the same time,
all datalogs and graphs containing the input will show no data for the duration of
the activation.
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.
Stabilization Time
The sensor needs some time to warm up on power-up. Enter the time delay on start-
up before the sensor signal is valid.
Units
Select the units of measure for the copper/nickel (g/l or oz./gal).
Name
The name used to identify the sensor may be changed.
Type
Select the type of sensor to be connected.

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 3000, and the dead-
band is 10, the alarm will activate at 3001 and deactivate at 2990.
