3. Job Set-up
Subtask 20-28-00-869-066-A

A. Equipment
(1) Use an OHMMETER MULTIRANGE, with the applicable leads and prods:

Set the ohmmeter range to a value that is higher than the maximum permitted value of the assembly that you will measure. Refer to (Ref. AMM TASK 20-28-00-869-002).
Set the tension to 500 VDC.

4. Procedure
Subtask 20-28-00-420-086-A

A. Measurement of the Electrical Resistance

CAUTION: MAKE SURE THAT YOU DO NOT CAUSE DAMAGE TO THE EQUIPMENT OR THE STRUCTURE WHEN YOU USE SHARP-POINT PRODS.

CAUTION: MAKE SURE THAT THE TEST EQUIPMENT IS CORRECTLY INSTALLED BEFORE YOU MEASURE THE BONDING VALUES.

(1) Connect the test equipment at the applicable locations (Ref. AMM TASK 20-28-00-869-002).
(a) Put one probe on the component.
(b) Put the other probe on the primary metallic structure.
(2) Measure the resistance value.
(3) Make sure that the measured values are not higher than the maximum permitted resistance values (Ref. AMM TASK 20-28-00-869-002).
(4) Disconnect the test equipment.
