1. Setup Menu
BASIC SETUP
There are 2 modes of operation available : Basic and Advance.
In Basic setup mode, LS4808 / 4816 shall detect the circuit for circuit fault automatically. The timing of detection shall
depend on the intervals set in Auto Detection mode, ( Refer to Auto Test section ). Follow the steps below to use this mode.

Note: In long cable circuit or zone with multiple branchings the basic mode may not be suitable to detect the fault such as short
at the far end of cable (e.g: 500m), cables itself has resistance, thereby would not show short phenomena. It is therefore,
Advance setup shall be used.
