Setpoint 
Touch the Setpoint [10.00g/L] button and enter the concentration at which the analyte will be regulated. 
Error Direction 
[Under] means that the user wishes to regulate to the set point in an environment where the analyte is being consumed 
and as such tends to fall under the set point. In this circumstance the control algorithm will attempt to regulate by making 
additions of correction feed stock (which contains the analyte) to the controlled volume. 
[Over] error direction assumes that the correction applied by the controller will have the effect of diluting or removing 
analyte to perform regulation. When [Over] is selected, enter the TPU manually. 
Example: In the case of a fermentation where glucose is the controlled analyte the user should select [Under] error 
direction since the organisms in the fermentation will consume glucose, thereby forcing the controller to add glucose via 
feed stock additions. 
Auto-Activation 
Auto-Activation automatically starts control once the sample value is within a certain percentage of the setpoint to 
minimize over/under correction. Using the default value, control will not start until the monitored sample value is within 5% 
of the setpoint. To change this value, touch the Auto-Activation [5.00%] button and enter the new value.  
When using Auto-Activation, make sure the monitored sample value is moving towards the setpoint value. If the monitored 
sample value is moving further away from the setpoint value, control will need to be started manually. 
TPU 
Time-Per-Unit error reflects the amount of time that the correction pump must run to correct for an error in concentration 
equal to the unit of measure (e.g. g/L, mg/L, etc.). 
Touch the [TPU] button. Select [Automatic] to allow the 2960 to calculate the TPU or [Manual] to enter the TPU manually. 
If your Error Direction is [Under], calculate the TPU manually.
