The manual is mute about its intended use as far as I can determine. I had thought that it might be an unassigned key that could be assigned to a custom program - its not. If it is meant to run one of the sub-routines on the module, I have not been able to figure out how it works.

Hi Steve,

I haven't used the 41 Control module, but I'm familiar with the 71B equivalent.

The CMD command is used to send commands to the 3421A. For example, if you wanted to set the 3421A to DC Volts and the 3V range you'd enter "F1R0" (Function 1, Range 0) in alpha and execute CMD. The equivalent for the 71B is CMD3421 and it combines the use of an OUTPUT and an ENTER statement.
