• Are offset parameters correctly configured ?
• Are there an incorrectly wired probe ?
For example, red and white wires are crossed ? This can happen when the probes are extended with cables having other colors, mixing then the order red-white red-white.
This problem happens also when you connect a probe which has less than 4 wires, and when the bridging is not made.
Depending on the resistance of the cable, the displayed values of the other channels may be shifted by several degrees. Such wrong connection make appear-100°C.
