Beginner friendly tutorial: How to modify the UNI-T UT210E Multimeter.
If you follow the steps in the video, you can modify your own Clampmeter, which will become way more individual and useful. Especially considering the low price.
That is what you need:

Optional, you can get a demagnetizer to reduce your DC-offset:

Benefits:
(1) Your meter can start up in DC-Mode, instead of AC-Mode for Voltage and Current
(2) Your meter will have a higher resolution - up to 10000 counts
(3) Your meter will start up in continuity measurement instead of resistance
(4) You can freely select your count range, measurement range, parameters for the meter to range up and down and in which order you want to select the modes.

The UT210E is also branded by Electronic companies.
Similar Meters with different functionality out of the box are those two:
- Voltcraft VC-337 (4000 counts up to 40A only)
- Extech MA63 (6000 counts up to 60A ony)
