The LM34 is driven by a circuit that converts the LM34's voltage to a
frequency that is read by a remote computer. The computer supplies the
circuit with a ground and +12V and receives a frequency on a third wire. The
circuit in turn supplies the LM34 with the same ground and 12v supply and
monitors the output voltage of the LM34.

it may be possible to modify the VCO (voltage to frequency circuit)
by raising its ground by one volt
OTOH can you account for the 1V offset by modifying the software to read the
frequencies differently?
