Current loop is stuck at 4 mA or
20 mA
On the current loop board, check the voltage
between the end of resistor R1 closest to the
jumper and ground. If the concentration reading
is high, the voltage should be near 1 VDC. If the
concentration reading is low, the voltage should
be near 4.7 VDC. If not, the problem is probably
on the HC12 main board. Return to factory for
service.
