the following three (3) steps.
7. Keeping the red (+) multimeter lead on the phase 1 AC terminal, place the black (-) multimeter lead on
the DC- terminal. The measured value should be open.
8. Place the black (-) multimeter lead on the phase 1 AC terminal and the red (+) multimeter lead on the
DC+ terminal and record the results. The measured value should be open.
9. Keeping the black (-) multimeter lead on the phase 1 AC terminal, place the red (+) multimeter lead on
the DC- terminal. The measured value should be 0.275V – 0.4V.
10. Repeat Steps 6 through 9 for the remaining Inverter phases.
NOTE
These values can vary depending on the meter being used. The main idea is that the values be consistent between phases.
