Dear All,?
Finally I collected all things for my 4274a with high voltage measurement.
The high voltage card working fine, but I can use it only on lower ranges in capacity mode.?
Video show what happen. Under 1uF looks like everything is okay but below 1uF I got Error 4. On the back the switch on the second position. =<2F
Video is here:
Whats wrong with the measure?
Thank you
Krisztian?
