Model 10C
6.0 Calibration
The 10C Controller’s conversion, of input current to a displayed value, can be trimmed up or down. Likewise,
the 10C Controller’s output current can be trimmed so that the Master Controller can register what is on the
10C Controller’s display. Each of the 4-20mA analog current input and the 4-20mA analog current output of
the 10C Controller may be trimmed independently. Both are calibrated at the factory and should require no
further adjustments. The independent trim is useful if the Master Controller cannot be itself trimmed and
instead small errors can be adjusted in the 10C Controller’s output current.
NOTE: Calibration of the sensor to standard gas is performed on the sensor itself, not the 10C
Controller. There is no “calibration” of the Controller, only “trim”.
Trim procedures are given in Trim Input, section 5.1, and Trim Output, section 5.2.
NOTE: The 10C Controller analog input and output is trimmed at the factory and under
normal circumstances should not need to be trimmed again.
