STE/lCE-R TEST PROCEDURES (Cont’d)
3. Readouts. The following paragraphs describe the different types of readouts that can occur during
testing.
(a) Status Readout. A status readout keeps the technician informed about what is happening. For
example, .8.8.8.8 is displayed each time the power switch is pushed on. It means that power is applied, and
that all elements of the display are operative. It changes to --- 1.5 seconds later, indicating that the VTh4 is
ready to be used for testing. The status readout displays are described in table 2-2.
(b) Prompting Message. A prompting message is a technician action message. It is a signal for you to
do something such as crank the engine. For example, UJZH tells you to enter the vehicle type identification
number into the VTM. After the technical action is performed, the test will automatically continue.
Prompting messages are listed in table 2-3.
(c) Numerical Readout. A numerical readout is the measured value in units of the measurement
being made. For example, if you are measuring O-45 volts DC, 12.7 is volts DC. If you are measuring O-25
psig pressure, 12.7 is psig. The units for each test are listed on the flip card. The numbers displayed in the
VTM are always positive unless there is a minus shown to make them negative.
