3. Place the meter probe on one phase of the AC input posts and the other meter probe on
another phase of the AC input as shown in Figure 51 (Measuring AC Input Voltage).
4. Verify that the meter shows the expected AC measurement within the range as indicated in
Table 16 (Expected AC Voltage Range).

5. If the meter does not show any reading, it is possible that there is no power from the VFD.
Measure again but this time verify the 3-phase output at the VFD.
6. If the meter still does not show any reading, ensure the AC power source is turned ON and try again.
7. If the measured values correspond to the specified values for all phases, the AC input voltage is okay.
