Seven TranScan FAQS
The temperature shown by the TranScan is different from the temperature shown by the fridge display. Does this mean that the recorder needs calibrating?
Almost certainly not. Each recorder is factory calibrated against traceable standards and accuracy of measurement of the TranScan system is normally within a few tenths of one degree Celsius.The most common cause of the two temperatures being different is that the sensing elements are in different locations within the fridge compartment. For example the fridge sensor is normally located in the air return ("air on") section of the evaporator and this is where we recommend that one of the TranScan sensors is located. If the fridge and the TranScan do not coincide first check that the sensors are in the same location and as near as possible to each other.
The TranScan will probably take readings from a second sensor located at the rear of the compartment in order to indicate air temperature distribution. This sensor will only show good correlation with the fridge sensor when the air circulation is good, a load at the correct temperature is present in the compartment and the fridge has been running long enough to allow the air temperature to properly stabilise.
