1. Connect the red testing probe to the jack signaled “V/Ω” for readings between
2 A and 20 A (maximum 10 seconds with 20 A) and the black to the jack signaled
“COM”.
2. Turn the knob to the maximum setting and reduce level by level depending
on the reading.
This function it is protected by a 2 A / 250 V fuse, however, pay special
attention to the range of 20 A, as it is not protected.
When using this range, the maximum reading must be 20 A, but not more than
15 s. or you can damage the internal resistances.
