This is a conflict monitor tester that is portable and  PC-based.  According to the accompanying documents it was last calibrated in 2008.  The unit may have been in storage since then and not used.  The software disc looks unused.  Not sure if it works on current Windows OS.   A brief look at the ATSI website revealed that they still may provide downloads for this model.  No cables are included other than attached power cord.  When plugged in the power light comes on.  That is all the testing we have done.
