>A final note: My DP10007 has a slight positive DC offset. Does anyone else see this?
I had a similar problem with my DP20003, more than 12V ofset (with the 200:1 range)
After complaint I got no new shiny probe, instead I got an email with the following instructions:
procedure for Micsig Auto-offset-calibration:
- connect probe to power (USB), switch on, short both input leads
- push down both range buttons simultaneous, after some time you will hear some relays clicking inside. The offset-error should be zero now
- switch off, switch on, test offset, be happy
- if my english is to bad: look at
