Meter Digital Mutimeter Voltage Amp Current Resistance Meter
1) when testing DC voltage, AC voltage, DC current resistance, diode, buzzer and battery, connect the red test lead to 'vo, mA' jack and black test lead to 'COM' jack.
2) when testing the current more than 200m A, connect the red test lead to '10ADC' jack and black test lead to 'COM' jack.
3) when testing the magnifying ratio of the transistor, tum the switch to hFE position and connect the transistor to the eight-hole jack.
4) sqaure wave output: the frequency is 50Hz, the voltage is approx 3Vp-p The output jack is 'V,0, mA' and 'COM
