It really depends on the outcome you want to achieve. If you are looking for instantaneous values, perhaps the clamp meter is a better option as you can move it around and easy to clamp onto different cables
. If you got a variety of shunts dependant upon the load being measured with say a 75mV output, these can be permanently wired into the system and connect a meter as required. At around say $10 each, not that expensive. Using Test plugs or a 2 pole selector switch, you could connect the relevant circuit to the panel meter.
Here is the page I came up with on Amazon
Obviously, if you are trying to measure 0.5A through a 20A shunt, the result won't be that accurate. Some give you instantaneous and wHrs as well.
In regard to the Chenglish, there is one meter listed as 0-100A on the front page, but investigating the specs, you find this
if measure the current over than 5A for long time. please welding the wires to the meter port, to avoid High impedance and unstable working. >
it is a 10A rated meter with internal shunt. Typo's happpppennnnn
