I. Safety Infor mation

Do not operate the tester if the body of meter or the test
lead look broken.
Check the main function dial and make sure it is at the
correct position before each measurement.
Do not perform resistance and continuity test on a live
power system.
Do not apply voltage between the test terminals and test
terminal to ground that exceed the maximum limit record in
this manual.
Exercise extreme caution when measuring live system with
voltage greater than 60V DC or 30V AC.
Keep the fingers after the protection ring when measuring
through the test lead.
Change the battery when the symbol appears to avoid
incorrect data.
