CHANGING THE SET VALUE (SP)
SENSOR CALIBRATION
This control function corrects the input value received from the sensor.
Often a sensor cannot be positioned where control is required. Due to the remote
location of the sensor the measuring value may deviate from the value measured at
the mid point of the working volume.
In such cases a correction value is entered at the controller shifting the input value of
the sensor.
This correction value is first entered when the equipment is under test at the factory.
Further small adjustments can be made by the operator to compensate for small
system calibration errors.
MEASURING EQUIPMENT
Ensure that the equipment used to verify the temperature at the desired location is
appropriate for the conditions, and it has a current certificate of calibration to a
traceable source issued by a registered organisation.
Use the up and down arrows
to change the Set Value(SP)
in the lower display. When
the desired SP is reached
leave for 2 seconds and the
digits will flash to confirm
entry.
The SP has been changed to
40.0 degrees in this image.
