I have code for the Fluke 8840A multimeter.  I don't know how similar the command set is.
 
My code is just a simple database that consists of 2 asyn records and 2 scalcout records.  I have appended it below.  This code does not allow changing the measurement type, etc.  That is just done once in the initialization.

Hi All,
Does anyone using Asyn driver for FLUKE 8508A multimeter?

Thank you,
