Keithley Instruments w/ multiple :INIT

Hello, my system includes a KE2400 and a KE2182A.  Parameters and setup is set for Delta mode with arm layer trigger count =1.  Using *OPC? or RQS allows me to identify when the buffer is filled and then I flush the readings.  I have the :INIT tied to a button so I can get readings when I ask. 

 

When using *OPC? the first set of readings are great but the following sets are repeated values .. (buffer doesn't get reset, for some reason)

 

When using RQS the first set of readings are great, but the following sets are all negative..

 

I want either of these systems to work... any ideas on how to debug and tackle this?

 

Dan
