8 – Troubleshooting and System Tests

3.

Check the resistance from the input leads to ground to verify that it reads as open. For all power supplies, the
resistance from input to ground should read as > 20 MΩ.



With the power disconnected and the ON/OFF switch (S1) set to OFF (

O

), all circuits

should read as open.



The electrical values shown are ±50%. However, this range is intended only for reference.
Resistance values can vary widely depending on the type of multimeter and the polarity
used to measure the readings.

4.

Check the output resistance for the values shown in the table.

Figure 6

If no problems were found during the visual inspection or the initial resistance check, and the power supply still does not
operate correctly, see the

Troubleshooting guide



The

Troubleshooting guide

on page 143 provides most probable causes and solutions.
