the meter only as specified in this manual; otherwise, the
protection provided by the meter may be impaired.
WARNING
To avoid possible electric shock, personal injury or death,

so use caution.
• Use appropriate personal protective equipment such as
safety glasses, 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
