CONTROL Instrument
The oven is equipped with a microprocessor based digital control instrument. The
Despatch CONTROL instrument has been configured as a proportional controller and
set to its optimum operating values. Initially, the CONTROL will allow the heater to
operate at full power. However; as the actual oven temperature reaches the setpoint,
the Proportional Control will cycle the heater on and off, minimizing process
temperature fluctuations.
