6. Reconnect the structure earth bonding cable to the lightning earth and measure and record

in column 5 the earth resistance reading.

7. Use a multimeter to measure the continuity between the inner and outer conductors of the

HVSC downconductor. The measurement should exceed 10,000 ohms.

8. Reconnect the HVSC lower termination to the lightning earth and re-seal the termination

using waterproofing tape to ensure that it is waterproof.

9. Report any problems arising from the above tests to your local LPI distributor for further

advice.
