Installation
•Ambient background temperature compensation from a second temperature sensor (infrared or contact temperature sensor) ensures extremely accurate results. For example, the output of the second unit, set for mV output, could be connected to the FTC2 analog input (0 to 5 VDC corresponding to low end and high end of temperature range) is utilized for real time compensation, whereby both sensors must be set on the same temperature range.
