AC/DC VOLTAGE MEASUREMENT

1. Insert the black test lead into the negative COM terminal and the red test lead into the positive

V terminal.

2. Set the function switch to the VAC or VDC position.

3. Use the MODE button to select AC or DC Voltage

4. Connect the test leads in parallel to the circuit under test.

5. Read the voltage measurement on the LCD display

DC CURRENT MEASUREMENT

1. Insert the black test lead banana plug into the negative (COM) jack.

2. For current measurements up to 4000uA DC, set the function switch to the uA position and insert

the red test lead banana plug into the (uA) jack.

3. For current measurements up to 400mA DC, set the function switch to the mA range and insert

the red test lead banana plug into the (mA) jack.

4. For current measurements up to 10A DC, set the function switch to the A position and insert the

red test lead banana plug into the 10A jack.

5. Press the AC/DC button until “DC” appears in the display.

6. Remove power from the circuit under test, then open up the circuit at the point where you wish

7.Touch the black test probe tip to the negative side of the circuit. Touch the red test probe tip to

the positive side of the circuit.

8.Apply power to the circuit.

9.Read the current in the display. The display will indicate the proper decimal point, value and

symbol.

AC CURRENT MEASUREMENT

1. Insert the black test lead plug into the negative (COM) socket.

2. For current measurements up to 10A, set the function switch to the A position and insert the red

test lead plug into the (10A) jack.

3. For current measurements up to 400mA, set the function switch to the mA range and insert the

red test lead banana plug into the (mA) jack.
