I would like to run both the Round and the EGT amplifier from 1 EGT sensor which is currently not possible.

With 300C degs in the exhaust ,both connected Amplifier shows 80-150C degs while the Round 10C degs.

When Amplifier GND disconnected (As per Marcel recomended)

both shows 1000C degs.

It would be desirable that both the Round and the Amp could work at the same time from the same EGT sensor.
