Visual inspection
A thorough visual check must be carried out before each electrical safety test.
Following items should be checked:
- Inspection of DUT for sign of damage.
- Inspection of flexible supply cable for damage.
- Any signs of pollution, moisture, dirt that can jeopardize safety. Especially
openings, air filters, protection covers and barriers must be checked!
- Are there signs of corrosion?
- Are there signs of overheating?
- Inscriptions and marking related to safety must be clearly readable.
- Installation of the DUT must be performed according to the Instruction manuals.
- During visual inspection the measuring points for the electrical testing have to be
determined too.
If the visual test passes, the instrument automatically proceeds with the next test in the
sequence.
If the visual test fails the user must evaluate if it is safe to proceed with the
measurements.
