DRB III Safety Information
DRB III SAFETY INFORMATIONWARNING: EXCEEDING THE LIMITS OF THE DRB III 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 DRB III 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 measurement 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 VDC or 500 peak VAC.
- Use cautio when measuring voltage above 25 VDC or 25 VAC.
- Use the lo 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) way from spark plug or coil wires to avoid measuring error from outside interference.
