Testing the Mustool MT8206 graphical multimeter
In this video I am testing another promotional product from Banggood.
I received a nice multimeter from them for testing. This multimeter is promoted as a “2 in 1 oscilloscope multimeter”. So, apart from the traditional multimeter functions, it also has an oscilloscope function, or at least features which remind us of an oscilloscope. I tested different features of it, for example the precision of the voltmeter at lower voltages (2.5 V, 5 V and 10 V from a voltage reference), its ability of measuring capacitance, current and resistance. The device passed these tests really well, I am especially satisfied with the voltage and current measurements, however, I think that the capacitance range could be extended more towards the lower end. I also tested how much the wire heats up at higher currents. I only tested the current at low voltages, but at 10 A and 10 V, the heating was acceptable.
Regarding the oscilloscope function, I have mixed feelings. The device behaved really well when I fed it with some clean periodic waves. However, the range of the graphical waveform function goes only up to 20 kHz. This might not be enough for many power applications where the switching frequency is within the range of 100-200 kHz. However, slower periodic signals are OK to observe. Another thing that I would like to emphasize is that we cannot control the voltage range in the “oscilloscope mode”, it seems to have an auto-range mode. The time scale can be changed but the value of the scale is not indicated anywhere. So, based on these missing features, I would not call this device an oscilloscope.
However, I would like to highlight its amazingly clear display. It has huge bright pixels which makes it very easy to read, even when a bright light is directed on the display. The clean display really makes it a good device.
