When testing DC voltage, AC voltage, DC current, resistance, diode, buzzer and battery, connect the red test lead to 'V 0 mA' jack and black test lead to 'COM' jack.
When testing the current more than 200mA, connect the red test lead to '' OADC' jack and black test lead to COM' jack
When testing the temperature, connect the temperealure probe to 'V, 0, mA' jack or 'COM' jack.
It can also be connected to the jack specialised for it.
When testing the magnifying ratio of the transistor, turn the switch to hFE position and connect the transistor to the eight-hole jack.
Square wave output: the frequency is 50Hz, the voltage is approx. 3Vp-p. The output jack is 'V, 0, mA' and COM'
