Temperature coefficient ( ) varies with environment temperature and material conductivity. It is supposed that the temperature coefficient of a material at 20 ℃ is coefficient ( ) at t ℃ will be as the following expression:

Types of Temperature Sensor
There are two temperature input types: PT500 and Analog Input.
PT500
Press the touch key T.SENS
to select the type of temperature input and select PT. The input type of the temperature is the platinum resistance temperature sensor. At this time, “PT500 temperature sensor” as standard in the instrument should be inserted into the temperature measurement input terminal.
Analog Input
Touch the T.SENS
soft key to select the temperature input type. AnLG_In is analog input (the range of the input voltage is 0-2V) and the corresponding forma is:
