a. The power for the operation of the test set is supplied by the
The STE-M1/FVS test set combines common and peculiar
The common hardware items are used for testing all the
vehicles that the test set supports.
This hardware is used in
requirements of the vehicle being tested.
For the purposes of this
subcourse, only the common hardware need be described in detail.
b. Common Hardware.
The common hardware items consist of a
vehicle test meter (VTM), a controllable interface box (CIB), a set
(1) Vehicle Test Meter.
The vehicle test meter (VTM) is the
basic unit to which the controllable interface box (CIB) and the set
its internal operation and the data inputs and outputs.
receives input power from the CIB. In the stand-alone mode, the VTM
is able to measure voltage, resistance, current, and frequency. The
VTM is a part of the VTM/Transducer Kit/Set Communicator Assembly
(figure 43 on the following page).
(2) Controllable Interface Box. The controllable interface box
(CIB) (figure 44 on page 61) is connected by cables to both the VTM
and to the vehicle being tested. The CIB has two identical 128 pin
connectors. When these connectors are used with the test cables and
peculiar hardware items, they connect to the vehicle test connectors
and active junctions.
multiplexing, communication, and power control. The CIB is a part of
the controllable interface assembly which also contains an adapter.
(3) Set Communicator.
The set communicator (SETCOM) is the
means by which the test set communicates information to the operator.
A keyboard allows the operator to communicate with the test set.
responses to observations, and commands to control the test progress.
