Wrangler 4WD L4-150 2.5L VIN P MFI (1998)
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 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 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
IN PUT LIMIT
Volts
0 - 500 peak volts AC
0 - 500 volts DC
Ohms (resistance)*
0-1.12 megohms
Frequency Measured
Frequency Generated 0 - 10 kHz
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 500v DC or 500 peak AC.
^
Use caution when measured voltage above 25v DC or 25v AC.
^
The circuit being tested must be protected by a 1OA 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 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 DRB away from spark plug or coil wires to avoid measuring error from outside interference.
