Measuring DC Voltage

This multimeter can be used to measure

DC voltages in the range from 0 to 1000V.

You can use this multimeter to do any DC

voltage measurement called out in the

vehicle service manual. The most com-

mon applications are measuring voltage

drops, and checking if the correct voltage

arrived at a sensor or a particular circuit.

To measure DC Voltages (see Fig. 7):

6. View reading on display - Note

range setting for correct units.

NOTE: 200mV = 0.2V

Measuring AC Voltage

This multimeter can be used to measure

AC voltages in the range from 0 to 750V.

To measure AC Voltages (see Fig. 8):

Fig. 7

1. Insert BLACK test lead into COM

test lead jack.

2. Insert RED test lead into

test lead jack.

3. Connect RED test lead to positive

(+) side of voltage source.

4. Connect BLACK test lead to nega-

tive (-) side of voltage source.

NOTE: If you don’t know which side

is positive (+) and which side is nega-

tive (-), then arbitrarily connect the

RED test lead to one side and the

BLACK to the other. The multimeter

automatically senses polarity and will

display a minus (-) sign when nega-

tive polarity is measured. If you

switch the RED and BLACK test

leads, positive polarity will now be

indicated on the display. Measuring

negative voltages causes no harm

to the multimeter.

5. Turn multimeter rotary switch to

desired voltage range.

If the approximate voltage is unknown,

start at the largest voltage range and

decrease to the appropriate range as

required. (See Setting the Range on

page 6)

1. Insert BLACK test lead into COM

test lead jack.

2. Insert RED test lead into

test lead jack.

3. Connect RED test lead to one side

of voltage source.

4. Connect BLACK test lead to other

side of voltage source.

5. Turn multimeter rotary switch to

desired voltage range.

If the approximate voltage is un-

known, start at the largest voltage

range and decrease to the appropri-

ate range as required. (See Setting

the Range on page 6)
