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.
