Yes i've manual that i've download from the site of Clarke Hess.If you want
i can email to you.
The problem is that if i set 100 mV,all time my DMM read a instable value
that oscillate continuosly from 100 to 99.5 to 101 to 99.3 etc.
In the other range the last digits are more stable.
I've tried to put the filter acrossss the input of dmm but nothing the value
is always oscillating,in a second it's change 3,4,5 times!!!!
Yes. I'd be very pleased if you could email it!. My address is ...

Sounds like the voltage 828 control loop itself is a bit unstable. Maybe a
My unit has some internal noise that is coming in from the 240Vac power
inlet (LO-GND connecting link 'on' or 'off' it's still the same) but not
the amount you are noticing.
PS: Just confirming my filter was wired as this ...
