F. Install the shunt cal resistor/connector assembly into the appropriate
slot of the SHUNT CAL connector on the front panel of the
appropriate I/O Carrier Module.
4. FlexTest IIm/CTC Controllers only: Install the shunt calibration resistor into
the R-Cal jacks in the appropriate DC conditioner.
You must know which DC conditioner is associated with the strain sensor.
You also need to know which of the two DC conditioners on the module is
used by your extensometer.
The shunt resistors for the Model 497.22 DC Conditioner are packaged in a
thumb-nail sized module. It makes it easier to install and remove the shunt
calibration resistor.
