4.2.4 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 below:
DRBIII® SAFETY FUCTIONAL LIMIT REFERENCE
| FUNCTION | INPUT LIMIT |
|---|---|
| Volts Volts | 0 - 500 peak volts AC |
| Volts Volts | 0 - 500 volts DC |
| Ohms (resistance)* | 0-1.12 megohms |
| Frequency Measured | 0 - 10 kHz |
| Frequency Generated | 0 - 10 kHz |
| Temperature Temperature | -58 - 1100°F |
| Temperature Temperature | -50 - 600°C |
* 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 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 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 test lead.
- 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.
