DRB III Safety Information

WARNING: EXCEEDING THE LIMITS OF THE DRBIII(R) MULTIMETER IS DANGEROUS. IT CAN EXPOSE YOU TO SERIOUS 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(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 below:
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 500 v DC or 500 v peak AC.
- Use caution when measuring 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.
