As the manual says, the output voltage should be between -2 and +2 V, but our measurement shows it is around 3.7 V.
It does change with the reading but only decreases down to around 3.4 V at full scale display at the front panel?
Other functions seem to be working OK.
What could have gone wrong with this 6485?
Any idea ?

Is it similar for each current range? Each range should be scaling it's full scale value to approximately +/-2V.
For open circuit condition on the Amp meter (0 Amps), what is the AO value then? Does it come close to zero?
Your instrument may need service.
