The resulting .S4K file can be converted to an AMP file for documentation. An example
of such an .AMP file is shown below.

The whole procedure takes typically 5-6 minutes. In the above example, some of the
conductors have resistance values around 22 Ohm, and some around 11 Ohm. This is because
of the fact that some conductors are connected in parallel, thus causing lower resistance
readings.

Special checks in the module “Test Software”
Check Cable Isolation.
Will check the cable spread for short circuit or leakage. Only one end of the cables should be
connected to the ES464 or ES10-64[C][e], and all takeouts must be isolated from the ground.
If using the two white Cable Joints, the outer two cables will only be partially tested. To
overcome this, run the test in two rounds with two cables each time. Alternatively replace the
white joints with electrically transparent (black) Cable Joints, part number 33 0019 35.
Auto Relay Test
Will set and reset every relay of the ES464. No cables should be connected. This is a lengthy
procedure, takes like 30 minutes.
Manual Relay Switching
Allows the user to set or reset any individual relay in the switch box. Useful for testing a
specific address (e.g. set an address and check for continuity with a digital multimeter) or for
taking a single reading in a cable spread.
