behind the finger guard of test leads

and the meter of the test leads.

8. During measurement, do not change

function switch of the meter nor replace

the plugs to other terminals.

9. Before starting measurement, make

sure that the function and range are

properly set.

10. Never use the meter when it is wet or

with wet hands.

11. Be sure to use the specified type of test
