DRB III Safety Information
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 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 V DC or 500 C peak AC.
-
Use caution when measuring voltage above 25 V DC or 25 V AC.
-
Use the low 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 away from spark plug or coil wires to avoid measuring error from outside interference.
