 Matters needing attention
 1.     The tester can't work in hot and humid conditions,please use i
 t in normal conditions;
 2.     This tester measures AC parameters, cannot used to measure DC
 parameters;
 3.     The tester's working voltage can't exceed AC**5V;
 4.     If work current greater than *0A or the load shorted could lea
 d to the fuse damaged, then need to replace a new *0A fuse;
 5.     Do not expose the tester to dusty , corrosive gases and other
 harmful substances in the environment when store and using;
 6.     Don't touch the meter except the panel, and it has high voltag
 e when using, or it will cause electric shock.
