I am using the 34970A with a 34901A in slot 1 with a 34904A in slots 2 and 3. I am using labview to run various tests some units. Recently I began to see error 914 come up constantly. When I change out the 34901A the error ceases to occur. I checked the code out in the manual and online and it tells me is that it is temperature sensor error but not what would cause it or how to fix it. Can some one please assist me.
