I would appreciate some information from someone who owns an original power supply for the DER EE DE-5000. Namely, I have two non-original 9V power supplies. What I can notice is that in the manual inductance measuring range (nothing attached), by touching the insulation of the alligator clips and moving them slightly, the device behaves as if it wants to measure a value - shows dashes. This condition normalizes after a few seconds. Obviously there is some interference, but I'm interested in whether this is the case with the original power supply. This does not happen when the device uses a 9 volt battery.
