Do not operate the meter around explo-
sive gas, vapor or dust.
Do not apply more than the rated volt-
age, as marked on the meter, between
terminals or between any terminal and
earth ground.
Before each use, verify the meter's op-
eration by measuring a known voltage.
When servicing the meter, use only
specified replacement parts.
Use caution when working above 30 V ac
