Square wave output:the frequency is 50Hz,the voltage is approx 3Vp-p.The output jack is "V ohm mA" and "COM"
When testing the magnifying ratio of the transistor ,turn the switch tohFE position and connect the transistor to the eight hole jack.
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 temperature probe to V 0 mA jack or COM jack. Please refer to the attached instruction manual for the operating instructions.
