Do I need to give a specific time for an inspection Wisconsin

[Alexandra Wenzel]

I own a rental in Wisconsin and I'm driving up this weekend to inspect.  I've let my tenant know that I'll be stopping by late morning or early afternoon to inspect.  My inherited tenant doesn't like me and has told me that according to Wisconsin law I need to give her 12 hours notice of a specific time.  I've never had any landlord give me a specific time for an inspection? Is this a thing or does a time window work? I've got a lot of other things going on that morning and don't know how long certain things will take so it's tough for me to say "I'll be there at 11"
