SUMMARIZE The meter is a stable multimeter with 26mm LCD display, driven by battery. It’s widely used on measuring DCV, ACV, DCA, ACA, resistance, capacitance, diode, transistor, continuity test and temperature. Ideal for lab, factory and family use. SAFETY NOTE The meter meets the standards of IEC1010.

3.2 DCV MEASUREMENT 1. Insert the black test lead to " COM " jack, the red one to V/Ω jack. 2. Set the range knob to a proper DCV range, connect the test leads across to the circuit under tested, the polarity and voltage of the point which red lead connect will display on LCD.
NOTE: 1. If the measured current is unsure beforehand, the range knob should be set to a higher range; then, switch to a proper range according to the display value. 2. If LCD displays "0L.", it means over range, the range knob should be set to a higher range.
2. When input terminal is in open circuit, overload displays. 3. When measuring in-line resistance, be sure that power is off and all capacitors are released completely. 3.8 CAPACITANCE MEASUREMENT 1. Insert the red test lead to " V/Ω" terminal and the black one to " COM " jack. 2.
3.11 TRIODE hFE 1. Set the range knob to hFE. 2. Insert the test accessory into “COM” and “mA” terminal. 3. Verify the type of the transistor is NPN or PNP, insert the emitter, basic and collector to the proper jack on test accessory. 3.12 NCV test (non-contact voltage detection) Turn the rotary switch to NCV position, and place the top of the meter approach the conductor.
