  • Page 140: Clock Configuration

    ProVU4 Controller, Profiler & Recorder/Controller - Product Manual As the jacket temperature rises, the slave’s heater output falls.

  • Page 141: Control Deviation

    ProVU4 Controller, Profiler & Recorder/Controller - Product Manual Control Deviation Control Deviation is the difference between the Process Variable value and the Actual Setpoint. The Control deviation error is equal to PV – SP. This value can be monitored using the bar-graph, and an excessive deviation warning can be given by using a deviation alarm.
