I can barely read AC/DC on the paperwork?? Does that mean it will read 12/24V amps drawn on car wiring as well a AC amps on house wiring?? If so it would a great addition for those folks who are trying to determine how many amps a circuit is pulling on their car. Treblig
It measures 400 amp and up to 1500 amp ac or dc. The dual range is for more accuracy in the 400 amp range. .1 amp-400 a ac/dc in thw 400 amp range, and 1a-1500 amp ac/dc in the 1500 amp range.
