Well from the specs in Amperes , DC looks 1% and AC 1.5% .
And I think that any one who cares for milliampere to Amperes, he will be ok.
And lets not forget the price.
And the bottom line is that you cannot do direct comparison,
with specs found in the expensive range of DMM !!
Just by looking at them, the U1233 looks to be like the cherry in the pie .
