Learning Event 4:
DESCRIBE CONSTRUCTION AND USE OF SIMPLIFIED TEST EQUIPMENT/
INTERNAL COMBUSTION ENGINE (STE/ICE)
CHARACTERISTICS
STE/ICE is a versatile tool for testing and taking measurements of vehicle engines as well as many
other types of electrical and mechanical equipment. In a protective transit case, complete with all
accessories, it is easily transported to a field site for general measurements and diagnostic connector
assembly (DCA) tests.
CAPABILITIES
STE/ICE has three major measurement capabilities:
General measurements
STE/ICE can be used to make standard voltage, current, resistance, pressure, and speed
measurements without specific vehicle or equipment information.
In making general
measurements, the vehicle test meter (VTM) receives power through power cable W5 or DCA cable
W1. Test data may be received through various test probe cables and transducers.
Special tests
STE/ICE can be used to test specific vehicles in the Army inventory. When a recognized vehicle
identification (VID) number is entered in the VTM, STE/ICE will automatically use vehicle
information stored in its memory together with test data to give a result. In performing special
tests, the VTM receives power from a battery through power cable W5 or DCA cable W1. Test
data may be received through various test probe cables and transducers.
Diagnostic connector assembly tests
If the vehicle or equipment to be tested has a permanently mounted DCA, the VTM can receive
both power and test data through DCA cable W1. Wires from the DCA connect to test points and
to the vehicle/equipment or power source. Additional transducers can be used at the same time for
test points not connected to the DCA.
