[volt-nuts] Fluke 335A

[J. L. Trantham]

My 335A is, seemingly, behaving but I have noticed two issues.

 

First, there is a slow fluctuation in the 'zero' reading and requires
adjustment every day or so to make it read 0.00000+/-.

 

Second, once adjusted, when set to 0.123456 volts, it fluctuates 2 or 3 uV
when monitored on an HP 3478A.

 

Are these behaviors normal?  If not, what suggestions are there to resolve
this?

 

Thanks in advance.
