     SAFETY INFORMATION 

1. 

Do not operate the tester if there is any sign of damage to the 
tester or the test leads. 

2. 

Check the main function dial and make sure it is in the correct 
position before each measurement. 

3. 

Do not perform resistance and continuity tests on a live power 
system. 

4. 

Do not apply voltage between the test terminals and test 
terminal to ground that exceed the maximum limits stated in this 
manual. 

5. 

Keep your fingers behind the protection ring on the test probes 
when using the test leads. 

6. 

Change the battery when the  

  symbol appears to avoid 

incorrect data.
