An other thought:
The manual says:
***
5. Press Hz% to obtain the frequency and duty cycle value.
   Input Amplitude: (DC electric level is zero)
   Input Amplitude:    >rangex30%
   Frequency response:UT61A and B <400Hz
                UT61C , UT61D andUT61E   <1KHz
***
I set the meter to the 10A range. Maybe that my input amplitude needs to be at least 3A (30%) in order to get a reading?

Hello all. Is this DMM still good value for a hobbyist at the $50 range, please (mainly for small battery testing and light electronics work). Thank you  :)

I believe it is, but watch out for the current ranges, the burden voltage is a bit high in some cases.

Thank you HKJ. I was wondering if the UT61E is decent for this kind of work:

It is, except for some measurements in mA and uA range, where the burden voltage is to high (Using an external resistor can fix that).
The problem ranges are 2200uA and 220mA, i.e. between 0 and 200uA it has very low voltage drop, same with 0 to 20 mA range.
