Measurement of the Surface Electrical Resistance of External Composite Panels with a Resistivity Test Set
1. Reason for the Job
You must measure the surface electrical resistance if you installed the panels after some modifications or repairs.
NOTE: The measurement of the surface electrical resistance is not necessary if the panels are installed subsequently to their removal without modifications or repairs.

A. General
(1) This is the recommended procedure for the measurement of the surface electrical resistance of an external composite panel (with or without non-conductive finish paint on the antistatic paint).
(2) As an alternative procedure, and only if there is no non-conductive finish paint on the antistatic paint, you can measure the resistance with an ohmmeter/megohmmeter (Ref. AMM TASK 20-28-00-720-011) or with conductive electrical tape (Ref. AMM TASK 20-28-00-720-011).

A. Measurement of the Surface Electrical Resistance
(1) Equipment
(a) The 5301-79-99ZZZ TEST SET, RESISTIVITY directly measures the surface electrical resistance of the antistatic paint on composite panels.
(3) Put the R1 probe on the panel.
(4) Measure the resistance:
(6) Remove the test equipment.
5. Close-up(1) Equipment
(a) The 5301-79-99ZZZ TEST SET, RESISTIVITY directly measures the surface electrical resistance of the antistatic paint on composite panels.
NOTE: You can do the measurement on panels with or without non-conductive finish paint on the antistatic paint.
NOTE: The equipment manufacturer instructions will tell you how to use the 5301-79-99ZZZ TEST SET, RESISTIVITY.
(2) If applicable, set the 5301-79-99ZZZ TEST SET, RESISTIVITY to mode R1. (3) Put the R1 probe on the panel.
(4) Measure the resistance:
- Make sure that the measured values are not higher than the maximum permitted values (Ref. AMM TASK 20-28-00-869-002).
(6) Remove the test equipment.
