10.0 Offset Calibration
After prolonged use the controller and/or thermocouple could require recalibration. A
quick check using an independent thermocouple and temperature indicator should be
made from time to time to determine whether full calibration is required.
For some processes the difference of just a few degrees can have negative
implications, so it is highly important that temperature readings are as accurate as
possible.
Note: All independent thermocouples and indicators should be calibrated and tested
prior to use to avoid incorrect calibration of your Carbolite Gero product.
10.1 Single-Point Calibration
When using an independent thermocouple and temperature indicator, the difference
between the readings on the product controller and the readings shown by the
independent temperature indicator should be considered the potential offset value.
This method can also be applied if the user wishes to measure the temperature at a
particular position of interest within the product, e.g. by their load / samples. The
difference between the temperature read by the control thermocouple and the
independent thermocouple by their samples could be calculated as the offset value.
For example:
If the controller is displaying a temperature of 1080°C, and the independent
thermocouple reads 1075°C, this means that the control thermocouple in the product is
reading an extra 5°C. This would make the offset value
-5 , as the controller needs to
display a temperature 5°C less than what it is currently displaying.
You can use the offset calibration function to adjust the temperature displayed on the
controller so that it gives a more accurate reading to a maximum of
-25 or +25 .
Note: It is possible to set offset values beyond the +/- 25 range,
however this is not recommended. If an offset value outside of this
range is required then it is likely that the thermocouple and/or
temperature controller require repair or replacement.
DO NOT operate the product if excessively high or low offset values
have been set as this increases the risk of damaging the product.
Contact Carbolite Gero Service for assistance.
To adjust the offset value:
Note: To adjust offset values the user must be logged in at Operator Level 3 or
higher.
