After taking several reading of the open connector, the program will prompt for the
standard resistor with a value between 50 ohms and 500 ohms. This resistor should be
mounted on a connector like those used during the open and short calibration steps. The
exact value is not critical. Enter the value you measured with a digital ohmmeter and
click Continue. If you are using the cal resistor that is included with your AIM, the
number printed on it should be entered. If you have a different cal standard, use that
value.
After reading the standard resistor, the Red LED goes off and the prompt for a
