  • Page 9: Dcv Measurement

    4.2 DCV MEASUREMENT 1.Insert the black test lead to “COM” jack, the red one to V/ jack. 2.Set the range knob to a proper DCV range, connect the test leads across to the circuit under tested, the polarity and voltage of the point which red lead connect will display on LCD. NOTE: 1.If the measured voltage is unsure beforehand, should set the range knob to the highest range, then, switch to a proper range according to the displayed value.

  • Page 10: Resistance Measurement

    4.5 ACV MEASUREMENT 1.Insert the black test lead to “COM” jack and the red one to“mA” jack（max. 200mA），or insert the red one to “20A” jack（max. 20A）. 2.Set the range knob to a proper ACA range; connect the test leads across to the circuit under tested. NOTE: 1.If the measured current range is unsure beforehand, should set the range knob to the highest range, then set to a proper range according to the displayed value.

  • Page 11: Diode And Continuity Test

    NOTE: 1.If the capacitance range under measured is unsure beforehand, should set the range knob to the highest range, then, set to a proper range according to the displayed value. 2.If LCD displays“1” , it means over range, should set the range knob to a higher range. 3.Before measuring, LCD display might not be zero, the residual reading will be decreased gradually and could be disregarded.
