  • Page 10: Operation

    OPERATION Before taking any measurements, read the safety information section. Always examine the instrument for damage, contamination( excessive dirt, grease, etc) and defects. Examine the test leads for cracked or frayed insulation. If any abnormal conditions exist do not attempt to make any measurement. VOLTAGE MEASUREMENT 1.Connect the black test lead to COM jack and the red test lead to V: jack.

  • Page 11: Resistance And Continuity Measurement

    2. For current measurements less than 400mA , connect the red test leads to the mA jack and the black test lead to COM jack. 3. For current measurements over 400mA or greater, connect the red test leads to the 10A jack and the black test lead to the COM jack.
  • Page 12 3. Connect the black test lead to COM jack and the red test lead to V: jack. 4. Touch the probes to the test points. In ohms, the value indicated in the display is the measured value of resistance. In continuity test, the beeper sounds continuously, if the resistance is less than 100:.

  • Page 13: Diode Test

    DIODE TEST WARNING: To avoid electric shock, do not test any diode that has voltage on it. 1. Connect the black test lead to COM jack and the red test lead to V: jack. 2. Set the function switch to the position.

  • Page 14: Frequency Measurement

    FREQUENCY MEASUREMENT WARNING: To avoid electric shock, discharge the capacitor under test before measuring. 1. Set the Function/Range switch to the “Hz” position. 2. Connect the red test lead to the n V jack. and the black test lead to the COM jack. 3.
