Volt and frequency
AC volt can measure up to about 2kHz (RMS will not work at the frequency).
AC volt with VFC reduces bandwidth to 400Hz and limits range to 200.0V & 600V
All ranges starts on AC
Input impedance is 10Mohm to 11Mohm on AC and DC
Buzzer sounds on over voltage (600V)
Current
Buzzer sounds on over current (100A).
All ranges starts on AC
As usual clamp meters are not very precise and at 0.5A and 5A it was about 2% out.
Ohm, Continuity, diode and capacity
Ohm is 1V open and 0.33mA shorted
Continuity is fast (Below 4ms).
Continuity beeps when resistance is below 50ohm.
Continuity is 1V open and 0.33mA shorted
Diode range uses 3.3V, max. display is 2.2V at 0.5mA, max. current is 1.4mA shorted
11000uF takes about 9 seconds to measure.
Miscellaneous
Current consumption of meter is 7.2mA (13.2mA with backlight) in current mode
Current consumption of meter is about 1.7mA (7.7mA with backlight) in other modes.
Meter works down to 2.2V where it turns off, battery symbol show at 2.5V.
Backlight only works down to about 2.6V where it is fairly dim.
Both current and voltage readings are stable with changing battery voltage.
The meter usual need a couple of display update to reach the final value.
Viewing angle is good.
Display updates around 3 times/sec
Backlight will automatic turn off in about 15 seconds.
Will automatic turn power off in about 15 minutes.
Weight is 174g without accessories, but with batteries.
Size is 174 x 62 x 32mm
Probes & clamp
Probe resistance 37mOhm for one.
Probe wire is 90cm long.
Clamp can handle up to ΓΈ17mm

Conclusion
This meter is nice for measuring 100's of mA or more without any voltage drop, using it for lower DC currents requires careful use of the zero button.
It has basic DMM functions, but it missing frequency and low currents.
It looks like it has real input protection and the CAT rating may be correct.

Very nice for a sub $20 clamp meter. UNI-T is definitely improving some of their low-end products nicely.
