3. Touch the test probe tips to the circuit under test. Be sure to observe the correct polarity (red lead to positive, black lead to negative). 4. Read the voltage in the display. The display will indicate the proper decimal point and value. If the polarity is reversed, the display will show (-) minus before the value. -
Page 13: Dc Current Measurements
DC CURRENT MEASUREMENTS CAUTION: Do not make current measurements on the 10A scale for longer than 30 seconds. Exceeding 30 seconds may cause damage to the meter and/or the test leads. 1. Insert the black test lead banana plug into the negative (COM) jack. -
Page 14: Ac Current Measurements
AC CURRENT MEASUREMENTS WARNING: To avoid electric shock, do not measure AC current on any circuit whose voltage exceeds 250V AC. CAUTION: Do not make current measurements on the 10A scale for longer than 30 seconds. Exceeding 30 seconds may cause damage to the meter and/or the test leads. -
Page 15: Resistance Measurements
RESISTANCE MEASUREMENTS WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any resistance measurements. Remove the batteries and unplug the line cords. 1. Set the function switch to the cap position. 2. -
Page 16: Diode Test
DIODE TEST WARNING: To avoid electric shock, do not test any diode that has voltage on it. 1. Set the function switch to cap position. 2. Press the MODE button until the symbol appears in the display. 3. Insert the black test lead banana plug into the negative (-) jack (COM) and the red test lead banana plug into the positive (+) jack (). -
