Gather for this segment — steps 10.17–10.23 (~25 min)
Other box
- C13 power cord ×1
Tools and consumables
- multimeter
Parts:
- multimeter · tool
Do: Confirm the C13 power cord is not plugged into the inlet and is not in the room. Set the meter to continuity/beeper and test it by shorting the probes.
Check
The meter beeps on a dead short. No cord anywhere near the machine.
What you're looking at
Nothing to look at on the machine; this step is about the meter and the absent cord. Continuity mode makes the meter beep whenever a conductive path joins its two probes, and that beep is the instrument for every measurement in this section.
LDO
"Incorrect wiring of AC/mains can be dangerous — therefore, always double check your work, and then triple check it once more." Do all seven steps, 10.17 to 10.23, in order. Do not skip ahead to the 24 V section.
Caution
Who is in the room, 00a.2: one adult at the machine for 10.17 to 10.23. She is out of the room until 10.24; at 10.23 nobody but the person with a hand on the switch is within reach of the machine.
