HKJ gave me the answer.

Seems like even though you can display Hz in DC Amp range the meter needs AC.
Wytnucls:
The book says no DC offset allowed when measuring frequency:

That table is for the frequency (Hz) position. In the above case frequency was measured on the current input, with DC selected.
Wytnucls:
No, that note covers all frequency selections.

Not as it stands, the frequency is only up to 1kHz when measuring it in the current ranges.
The note "DC electric level is zero" must mean that it only works for AC, not pulsing DC. In the "fast" test I made it was not critical with DC offset, but it needed something below zero to work.
