How the correct way to have typical cheap DMM read AC V hertz as it'll display 000 as long as the either/both probe connected and a frequency, here in kilohertz, if it's disconnected, so what is the correct time length of the probe being connected before DMM gives a read frequency ?
Problem is it seems the frequency given is inconsistent, varies on that time length of the probe being connected and problem too it's shown in short time while the "max/min" feature cannot be applied in this Hertz selection
Please sincerely help of which the correct guide is really appreciated
