OPERATING THE FAST-CAL
FRONT PANEL LAYOUT
The Temperature Controller
The controller has a dual display, the upper display indicates the nominal block temperature, and the lower display indicates
the desired temperature or setpoint.
Altering the Setpoint
To change the setpoint of the controller simply use the UP and DOWN keys to raise and lower the setpoint to the required
value. The lower display changes to indicate the new setpoint.
ADVANCED CONTROLLER FEATURES
Setpoint Ramp Rate
By default the Dry Blocks are configured to heat and cool as quickly as possible. There may be some calibration applications
where it is advantageous to limit the heating or cooling rate.
An example might be when testing bimetallic thermostats; by forcing the Dry Block to heat at a controlled rate it is easier to
determine the temperature at which the thermostat changes state.
The Dry Block can have its heating rate limited with the Setpoint Ramp Rate feature. This feature is accessed from the
Scroll key. Depress the key until the display shows,
SP.RAT
The upper display will show the current value, and is adjustable from OFF to 999.9. The units are °C/min and are adjustable
via the UP/DOWN keys.
When the SP.RAT is active the lower setpoint display will now automatically update with the current value, known as the
working setpoint. The setpoint can be seen by pressing either the UP and DOWN key.
The Setpoint ramp rate operates when the bath is heating and cooling.
