Safety

1. Circuits under test must be de-energized and isolated before connections are made (except for

voltage measurements).

2. Circuit connections must not be touched during a test. Use extreme caution when working near

bare conductors and bus bars. Accidental contact with conductors could result in electrical

shock.

3. Use caution when working near voltages above 60VDC or 30VACrms.

4. After insulation tests, capacitors must be discharged.

5. Test leads (including alligator clips) must be in good working order, clean and without broken

or cracked insulation.
