1. Set the function switch to the V position (“mV” will appear on the display). The device will automatically

select DC.

2. Insert the black test lead banana plug into the negative (COM) jack and the red test lead banana plug into

the positive (V) jack.

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 on 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.

AC VOLTAGE MEASUREMENTS

1. Set the function switch to the V position. Press MODE to select AC voltage.

2. Insert the black test lead banana plug into the negative (COM) jack and the red test lead banana plug into

the positive (V) jack.

3. Touch the test probe tips to the circuit under test.

4. Read the voltage in the display. The display will indicate the proper decimal point, value and symbol (AC,

V, etc.).

DC CURRENT MEASUREMENTS

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

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

test lead banana plug into the (µ A) 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 MODE button until “DC” appears in the display.

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

measure current.

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 on the display. The display will indicate the proper decimal point, value and symbol.

WARNING:

Risk

lectrocution. The probe tips may not be long enough to contact the live parts inside

some 240V appliance outlets because the contacts are recessed deep in the outlets. As a

result, the reading may show 0V when the outlet actually carries voltage. Make sure the

probe tips are touching the metal contacts inside the outlet before assuming that there is no

voltage is present.

CAUTION:

Do not measure AC voltages if a motor on the circuit is being switched ON or OFF. Large

voltage surges may occur that can damage the meter.

CAUTION:

Do not carry out current measurements on the 10A scale for a period longer than 30

seconds. Exceeding 30 seconds may cause damage to the meter and/or the test leads.
