DISCLAIMERS

All information, illustrations, and specifications

contained in this manual are based on the latest
information available at the time of publication.
The right is reserved to make changes at any time
without notice.

SAFETY

4.2.1

TECHNICIAN SAFETY INFORMATION

WARNING: ENGINES PRODUCE CARBON
MONOXIDE THAT IS ODORLESS, CAUSES
SLOWER REACTION TIME, AND CAN LEAD
TO SERIOUS INJURY. WHEN THE ENGINE IS
OPERATING, KEEP SERVICE AREAS WELL
VENTILATED OR ATTACH THE VEHICLE
EXHAUST SYSTEM TO THE SHOP EXHAUST
REMOVAL SYSTEM.

Set the parking brake and block the wheels before

testing or repairing the vehicle. It is especially
important to block the wheels on front-wheel drive
vehicles; the parking brake does not hold the drive
wheels.

When servicing a vehicle, always wear eye pro-

tection, and remove any metal jewelry such as
rings, watchbands or bracelets that might make an
inadvertent electrical contact.

When diagnosing a chassis problem, it is impor-

tant to follow approved procedures where applica-
ble. These procedures can be found in the service
manual. Following these procedures is very impor-
tant to the safety of individuals performing diag-
nostic tests.

4.2.2

VEHICLE PREPARATION FOR
TESTING

Make sure the vehicle being tested has a fully

charged battery. If it does not, false diagnostic codes
or error messages may occur.

4.2.3

SERVICING SUB-ASSEMBLIES

Some components of the chassis system are in-

tended to be serviced as an assembly only. Attempt-
ing to remove or repair certain system sub-
components may result in personal injury and/or
improper system operation. Only those components
with approved repair and installation procedures in
the service manual should be serviced.

4.2.4

DRBIII

T

SAFETY INFORMATION

WARNING: EXCEEDING THE LIMITS OF THE
DRBIII

T

MULTIMETER IS DANGEROUS. IT

CAN

EXPOSE

YOU

TO

SERIOUS

OR

POSSIBLY

FATAL

INJURY.

CAREFULLY

READ AND UNDERSTAND THE CAUTIONS
AND THE SPECIFICATION LIMITS.

Follow the vehicle manufacturer’s service speci-
fications at all times.

Do not use the DRBIII

t

if it has been damaged.

Do not use the test leads if the insulation is
damaged or if metal is exposed.

To avoid electrical shock, do not touch the test
leads, tips, or the circuit being tested.

Choose the proper range and functions for the
measurement. Do not try voltage or current mea-
surements that may exceed the rated capacity.

Do not exceed the limits shown in the table below:

FUNCTION

INPUT LIMIT

Volts

0 - 500 peak volts AC
0 - 500 volts DC

Ohms (resistance)*

0 -1.12 megohms

Frequency Measured
Frequency Generated

0 - 10 kHz

Temperature

-58 - 1100°F
-50 - 600°C

* Ohms cannot be measured if voltage is present.

Ohms can be measured only in a non-powered
circuit.

Voltage between any terminal and ground must
not exceed 500v DC or 500v peak AC.

Use caution when measuring voltage above 25v
DC or 25v AC.

Use the low current shunt to measure circuits up
to 10A. Use the high current clamp to measure
circuits exceeding 10A.

When testing for the presence of voltage or cur-
rent, make sure the meter is functioning cor-
rectly. Take a reading of a known voltage or
current before accepting a zero reading.

When measuring current, connect the meter in
series with the load.

Disconnect the live test lead before disconnecting
the common test lead.

When using the meter function, keep the
DRBIII

t

away from spark plug or coil wires to

avoid measuring error from outside interference.
