GENERAL
The meter is a stable 4 1/2 multimeter with LCD display, driven by battery. It's widely used on measuring DCV,
ACV,
DC current, AC current, resistance, conductance, capacitance, diode, transistor, continuity test and fr equency, and has the function of overload pro tection, auto power off and data hold, etc.

SAFETY
Meet with I EC1010 standard Read the safety note before operation. 2-1 Do not input a limited value over-ranged. 2-2.The voltage below 36V is safety.Toavoid electric shock, check whether the test lead s are connected correctly, whether the insulation is good when measuring over 36 V DCV or 25VACV. 2-3 The test leads should be removed from the testing point when changing function and range. 2-4 Choose correct function and range to avoid wrong operation. 2-5 Do not take m easurement if the battery is not fit on or rear cov er ked. 2-6. Do not input v oltage when measuring resistance. 2-7. Remov e the test leads and turn the power off before replacing battery or fuse. 2- 8 Specification of safety sig nal
