2.1: Description of the system:
Futura’s Cable Harness Tester (CHT
),
is designed to test Cable Harnesses,
Cable Looms, Cable Forms. CHT locates interchanged connections, shorted
connections, open connection and extra points. CHT facilitates two stage testing of
harnesses.
CHT is a 16 bit Digital Signal Controller based stand alone unit; and
Hence testing speed has been enhanced as compared to older version. Time
taken to test depends on factors such as selected mode (auto / manual), extra point test,
number of points etc.
Minimum test system consists of Harness tester with mounting board / rig.
Complete test system consists of tester, a mounting rig, solid state Floppy, PC, printer or
stamping unit.
Harness tester is connected to the Rig
(Jig)
through “
D
” type connectors. Any
point on rig can be connected anywhere; meaning there is no “
From
” and “
To
” concept.
This simplifies the rig wiring to a great extent. This concept also facilitates in indirect
saving of space by accommodating different types of harnesses on the same mounting
rig. While designing the rig; care should be taken that all the end points or mountings of
all harnesses are taken on the board. Each mounting is connected to the tester. A harness
is mounted at particular mountings while learning the data as well as testing.
The harness to be tested is mounted on the rig and then tested through tester.
The errors can be seen on tester’s
LCD
display.
