DRBII Safety Information

WARNING: Exceeding the limits of the DRB multimeter is dangerous, it can expose you to serious or possibly fatal injury. Carefully read and understand the cautions and specifications limits.

^ Follow 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 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:

FUNCTION INPUT LIMIT

Volts 0 - 500 peak volts AC
0 - 500 volts DC

ohms (resistance)* 0 - 1.12 megaohms

Frequency Measured 2 - 10 kHz
Frequency generated

Temperature -58 - 1100°F
-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 500 volts DC or 500 volts peak AC.

^ Use caution when measuring voltage above 25 volts DC or 25 volts AC.

^ The circuit being measured 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 curent, make sure the meter is functioning correctly. Take a reading of 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 functions, keep the DRB away from spark plug or coil wires to avoid measuring error from outside interference.
