keysight dmm 34461a data logging problem

I bought this 12 years ago and realised that I had been conned.  I was led to believe that it would perform basic data logging functions.  It turned out not to have the data log function under acquire. I could only get a trigger delay setting supposedly to set the interval time between samples. this turns out to be very hit and miss and I end up with thousands of samples over a 24hr period. Huge waste of time on a spreadsheet.  Anyone know how to tame this beast.  I would like say 1s/6mins  for a 48 hr record  on a 24v reading.  OBTW I messed with Benchview and was appalled at the shoddy software - it would talk via usb properly I wasted months trying to get it to work.  All hot air and promises from Agilent in the states.  Very disappointed in their communication s/w

Try TestController, it can easily do it, even 48 hours with a entry each second.

You hint at what you are expecting, but aren't totally clear.  Are you wanting it to take a sample every second but only record it if there is a certain amount of change from the last sample?  And then record at least one sample every 6 minutes even if there is no change?  That is a feature that is not universal even to instruments that feature data logging.  Once you've had and used it, it does seem like everyone should have it, but alas...

You can, sort of, do that with TestController. You must record all data, but during export you can reduce the data based on change.
