CAUTION
To protect yourself, think “Safety First”:
• Comply with local and national safety codes.
• Use appropriate personal protective equipment such
as face shields, insulating gloves, insulating boots,
and/or insulating mats.
• Before each use:
- Perform a continuity test by touching the test leads
together to verify the functionality of the battery
and test leads.
- Use the 3 Point Safety Method. (1) Verify meter
operation by measuring a known voltage.
(2) Apply
meter to circuit under test. (3) Return to
the known
live voltage again to ensure proper operation.
• Always work with a partner.
