DIGITAL MULTIMETER DIGITAL DIGITAL MULTIMETER OPERATION MULTIMETER OPERATION OPERATION MANUAL

1. 1. 1. GENERAL

GENERAL 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 frequency, and has the function of
overload protection, auto power off and data hold, etc.

2. 2. 2. SAFETY

SAFETY SAFETY
Meet with IEC1010 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. To avoid electric shock, check whether the test leads
are connected correctly, whether the insulation is good when measuring over 36VDCV 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 measurement if the battery is not fit on or rear cover ked.
2-6. Do not input voltage when measuring resistance.
2-7. Remove the test leads and turn the power off before replacing battery or fuse.
2-8．Specification of safety signal
" " existing dangerous volt " " GND " "dual insulation
" "operator must refer to the manual" "low battery indication
