The correct way to have DMM read AC V hertz

[abdulbadii]

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

Keep both probes connected until you get a stable reading for a few seconds.

If you do not get a stable reading (on a consistent signal) then the meter is incapable of measuring it, eg. due to too high frequency or too low signal level.
