And one more confusion there at 4:47. The calculation is wrong, doesn't correspond to the formula. PI should have been 120.3/114.1= 1.05 and not 0.94. Right?
But the value the IP is low, according to the table, it is still low and in danger, is correct triste meassure in this equipament chinese or they do not measure well,?
others I tester form this "higt value" brand (es: mh10) has L and E terminal reversed, maybe they are on mh12 to but the labels on the terminal are incorrect
