I posted a question in this forum on 28 Oct 2002 regarding a HP9114a unit I had just received. With your help I found out that I had the right power supply. Unforunatly, the battery was apparently dead because the fault light was on. So, after a little research, I found that in my location "Interstate Batteries" had an equivalent replacement battery for around 25 $Cdn. I received and install the unit and everything now works fine !
Thanks for your help !
