DRBIII SAFETY INFORMATION
WARNING: EXCEEDING THE LIMITS OF THE
DRBIII 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 specifications at all times.
^ Do not use the DRBIII 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 function for the measurement. Do not try voltage or current measurements that may exceed the rated capacity.
^ Do not exceed the limits shown in the table.
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 measured voltage above 25v DC or 25v AC.
^ The circuit being tested must be protected by a 10A fuse or circuit breaker.
^ 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 current, make sure the meter is functioning correctly. 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 away from spark plug or coil wires to avoid measuring error from outside interference.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
