About this item

• 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.
