OPERATION MANUAL
SUMMARIZE
The instrument is a stable digital multimeter driven by battery. It comes
with 20mm high LCD to make reading more clear. Backlight display and
overload protection make it convenient to use .This instrument features multi
functions for measuring DCV, ACV, DCA,ACA, resistance, capacitance,
diode, continuity and frequency., The instrument utilizes a dual-integral A/D
converter as a key feature and is an excellent tool. It is portable and Ideal for
lab, factory and field use.
SAFETY NOTE
The meter meets the standards of IEC1010.
Please read the operation manual carefully before operation.
1． Do not input anything over a range limit.
2． Voltage below 36V is safe. To avoid electric shock, check whether the test
leads are connected correctly, whether the insulation is good when
measuring over 36DCV or 25ACV.
3． Remove the test leads when changing function and range.
4． To select correct function and range, make sure the range limit setting is
correct. Start with higher limits and work down to correct level if uncertain.
5． Do not operate the meter if battery case and back cover is not properly fixed.
6． Do not input voltage when measuring resistance.
7． Remove test leads from test point and turn off the power before replacing
battery and fuse.
