The control board contains the Analog/Digital con-
verter, the Signal Conditioner and other compo-
nents.
The function of the Signal Conditioner is amplifier
and make the linearisation of the signal received
from the sensor and there is one Signal Conditioner
for every model of RTD or Thermocouple sensor.
The trimmers for Span and Zero are also located on
the Signal Conditioner. Use these trimmers only for
calibration procedure.
