7. Be sure to use a fuse of the specified rating or type. Never use

a substitute of the fuse or never make a short circuit of the fuse.

8. When connecting and disconnecting the test leads, connect

the ground lead (black one) first. When disconnecting them,
the ground lead must be disconnected last.

9. Always keep your fingers below the finger guards on the

probe when making measurements.

10. Be sure to disconnect the test pins from the circuit when

changing the function.

11. Before starting measurement, make sure that the function and

range are properly set in accordance with the measurement.

12. Never use meter with wet hands or in a damp environment.
13. Do not use the device near an item of strong electromagnetic

generation or a charged item. 

14. Never open tester case except when replacing batteries or

fuse. Do not attempt any alteration of original specifications.

15. To ensure safety and maintain accuracy, calibrate and

check the tester at least once a year.

16. The multimeter is restricted to indoor use only.
