The following steps check basic current functions with a short across the power
supply's output.
Power
1 Turn on the power supply.
The power supply will go into the power-on / reset state; the output is disabled (the

2 Connect a short across (+) and (-) output terminals with an insulated test lead.
Use a wire size sufficient to handle the maximum current (See "Table 7-1 Wire Rating"
on page 153 in chapter 7).
