I'm using a FP-RTD-122 module with PT-100 sensors to measure temperatures in a kiln. Whilst calibrating the system I found that all of the channels in the fieldpoint module appear to have an offset of approx 4 degrees celcius from the actual temperature. The temperature read by the RTD is measured by a Fluke meter at the point where the wiring is connect to the FP base so any offset due to the cabling should be the same for both readings.
Also the offset seems to disappear when the module is hot unplugged and replugged, but reappears after the power to the FP system is cycled.
The module is connected to an FP-2000 controller running LV RT 6.1.1 and with the latest firmware and FP Explorer 3.0.2
