4.1 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.
4.2 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 the vehicle; the
parking brake does not hold the front drive wheels.
When servicing a vehicle, always wear eye pro-
tection, and remove any metal jewelry such as
watchbands or bracelets that might make an inad-
vertent electrical contact.
When diagnosing an antilock brake or speed
proportional steering system 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 diagnostic 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 antilock brake or speed
proportional steering system are intended to be
serviced in assembly only. Attempting to remove or
repair certain system sub-components may result
in personal injury and/or improper system opera-
tion. Only those components with approved repair
and installation procedures in the service manual
should be serviced.
4.2.4 DRBIII SAFETY INFORMATION
WARNING: EXCEEDING THE LIMITS OF THE
DRBIII MULTIMETER IS DANGEROUS. IT
CAN EXPOSE YOU
POSSIBLY FATAL
READ AND UNDERSTAND THE CAUTIONS
AND THE SPECIFICATIONS LIMITS.
•
Follow the vehicle manufacturer's service speci-
fications at all times.
• Do not use the DRBIII if it has been damaged.
•
Do not use the test leads if 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 function 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
Volts
Ohms (resistance)*
Frequency Measured
Frequency Generated
Temperature
* Ohms cannot be measured if voltage is
present. Ohm 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 test lead.
•
When using the meter function, keep the
DRBIII away from spark plug or coil wires to
avoid measuring error from outside interference.
