Make sure that the test leads are plugged into the correct sockets. The black test lead should be plugged into the black
socket (sometimes, this socket is also marked by a " - ", or "E" or marked as "COMMON" or "COM"). The red test lead
should be plugged into the red socket marked with "+", "V" or "Ω".
2
When making measurements ensure that the test probes have a good clean contact with bare metal, free from grease,
dirt, and corrosion as these can cause a false reading.
3
When measuring voltage:
Make sure that the correct range is selected, that is set the selector to a value equal to or greater than that you are about
to measure.
e.g. If asked to measure 12 Volts, set the selector to the 12V range. If there is no 12V range, set the selector to the next
range higher, 20V for instance.
If the meter is set to a range that is too low, it may be damaged.
e.g. setting to the 2V range to measure 12V.

Electrical Testing Methods
- Using a Multimeter
1
Measuring DC Voltage
a On the FLUKE 85
Turn the switch to position B.
b On the AV0 2003
Move the right slider switch to position A, and the left hand slider switch to the appropriate range.
c On an analogue meter
Turn the dial to the appropriate DC Volts range.
Connect the black probe to the nearest available suitable earth point, usually this will be the starter motor earth, the battery
negative, or the chassis. Connect the red probe to the wire or contact from which you are measuring the voltage.
2
Measuring Resistance
Make sure there is no power to the part of the circuit you are about to measure.
Connect one probe at one end of the component or wire to be checked and the other probe at the other end. It does not
matter which way round the two probes are placed.
a On the FLUKE 85
Turn the switch to position C and check that the Ω sign at the right hand side of the display window is on. If the F
sign is on instead, press the blue button G to change the reading to Ω.
Touch the meter lead probes together and press the REL ³ key on the meter to eliminate the lead resistance from the
meter reading.
b On the AV0 2003
Move the right hand slider switch to position B, and the left hand slider switch to the appropriate Ohms (Ω) range.
c On an analogue meter
Move the dial to the appropriate Ohms (Ω) range.
3
Measuring Continuity
Make sure there is no power to the part of the circuit you are checking for continuity.
Connect one probe to one end of the component or wire to be checked and the other probe to the other end. It does not
matter which way round the two probes are placed.
a On the FLUKE 85
Turn the switch to position C and check that the beeper symbol appears at the left hand side of the display window.
If the F sign is on instead, press the button labelled F in the meter drawing.
If there is continuity in the circuit, the beeper will sound. If there is no continuity (open circuit), the beeper will not
sound.
b On the AV0 2003
Move the right hand slider switch to position B, and the left hand slider switch to position C.
If there is continuity (i.e. very low resistance) between two points the buzzer will sound.
c On an analogue meter
Turn the dial to the lowest Ohms (Ω) range.
If there is continuity (i.e. very low resistance) between two points the needle will move across fully (or almost fully) to
the right hand side of the scale.

Testing a Diode or a Diode Wire
A diode wire is a diode with male connector fitted on one end and a female connector fitted on the other end. The diode is
sealed in heatshrink sleeving.
a
On the FLUKE 85
Turn the switch to position D.
Press the HOLD button and check that the H sign appears at the top right hand side of the display window.
Connect the black probe to the end of the diode with a band or to the male connector of the diode wire. Connect
the red probe to the other end of the diode or diode wire. If the beeper does not sound the diode or diode wire is
faulty.
Connect the red probe to the end of the diode marked with a band, or to the male connector of the diode wire, the
black probe should be connected to the other end of the diode or diode wire. If the beeper sounds or the meter does
not read O.L., the diode or diode wire is faulty.
Press the HOLD button and check that the H sign disappears from the right hand side of the display window.
b
On the AV0 2003
Move the right hand slider to position A, and the left hand slider switch to position C.
Connect the black probe to the end of the diode marked with a band, or to the male connector of the diode wire, the
red probe should be connected to the other end of the diode or diode wire. If the Avometer does not buzz the diode
is faulty.
Connect the red probe to the end of the diode marked with a band, or to the male connector of the diode wire, the
black probe should be connected to the other end of the diode or diode wire. If the Avometer does not read "1" the
diode is faulty.
c
On an analogue meter
Select the Ohms 1000s (1k) range.
Connect the black probe to the end of the diode marked with a band, or to the male connector of the diode wire, the
red probe should be connected to the other end of the diode or diode wire. The meter should read 20-400 KΩ, if it
reads more than this the diode is faulty.
Select the Ohms 100s range.
Connect the red probe to the end of the diode marked with a band, or to the male connector of the diode wire, the
black probe should be connected to the other end of the diode or diode wire. The meter should read 300-400Ω, if it
reads less than this the diode is faulty.
