DRBIII Safety Information

WARNING: Exceeding the limits of the DRB multi-meter is dangerous. It can expose you to serious or possible 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 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 other circuits 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:

INPUT LIMITS

Function

Input Limit

Volts

0-500 Peak Volts AC, 0-500 Volts DC.

Ohms (Resistance) ⁽¹⁾

0-1.12 Megohms

Frequency Measured

0-12 kHz

Frequency Generated

0-10 kHz

Temperature

-58 - 1100°F (-50 - 600°C)

⁽¹⁾	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 volts DC or 500 volts peak 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 cur rent, 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 DRB away from spark plug or coil wires to avoid measuring error from outside interference.
