How do you measure the resistance and voltage on your mobile phone board with a multimeter?
If the measured resistance exceeds the maximum of the selected range, the meter will show "1", and a higher range should be selected. Measurement of resistance, the red pen is positive, the black pen is negative, and this is the opposite of pointer multimeter. Therefore, measurement of transistor, electrolytic capacitors and other polar components, must pay attention to the polarity of the pen
Table measuring resistance: mobile phone switch to the appropriate range range of Omega, the red pen is inserted into the V / Omega hole, the black pen insertion hole COM.
Mobile phone with a multimeter measuring voltage, AC and DC voltage measurement: according to the needs of the measuring range switch to DCV (DC) or ACV (AC) in the appropriate range, the red pen is inserted into the V / Omega hole, the black pen is inserted into the COM hole, and the pen and the measured line in parallel, the reading is displayed.
