DRB III Safety Information
WARNING: EXCEEDING THE LIMITS OF THE DRBIII(R) MULTIMETER IS DANGEROUS. READ ALL DRBIII(R) INSTRUCTIONS BEFORE USING THE MULTIMETER. FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN PERSONAL INJURY OR DEATH.
- Follow the vehicle manufacturer's service specifications at all times.
- Do not use the DRBIII(R) 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
- Voltage between any terminal and ground must not exceed 500 v DC or 500 v peak AC.
- Use caution when measured voltage above 25 v DC or 25 v AC.
- The circuit being tested must be protected by a 10 A fuse or circuit breaker.
- Use the low current shunt to measure circuits up to 10 A. Use the high current clamp to measure circuits exceeding 10 A.
- 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(R) away from spark plug or coil wires to avoid measuring error from outside interference.
- Follow the vehicle manufacturer's service specifications at all times.
- Do not use the DRBIII(R) if it has been damaged.

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