VTM READOUT

INTERPRETATION

.8.8.8.8

A readout of .8.8.8.8 appears for 1 to 2 seconds each time power is applied to the VTM.

It means that there is power to the VTM and all elements of the readout display are

operative.

----

A readout of four dashes indicates the following:

1. After power is turned on, it signifies that the VTM is ready for testing.

2. During a compression unbalance test, it signifies testing is in progress.

3. During battery condition test, it signifies battery may be in discharged state.

.9.9.9.9

A readout of .9.9.9.9 indicates that the VTM is reading a test value beyond the range of

its measurement. Either the wrong test number is selected for parameters being

measured or there is a fault in the vehicle. During a battery condition test, it signifies a

bad connection condition or discharged or bad batteries.

PASS/FAIL

Pass or Fail readout is the outcome of a test that checks the condition of a component

being measured. A Pass/Fail readout means the component either passes or fails the

test.

INTERPRETATION

UEH

Signal to technician to enter Vehicle Identification (VID) numbers on the Test Select

switches. VID numbers are found under test data on the flip-cards, on vehicle test

cards, and in the appendix of TM 9-4910-571-12&P.

During the battery condition test, indicates a weak battery in series pair of batteries

being tested.

CIP

CAL

Signal to technician to release the TEST button during an offset test.

Numbers are used for prompting messages. For example, in the confidence test, 66

signals the technician to dial in 99. In C1 acceleration/deceleration power test No. 12,

the first numerical readout signals the technician to shut off fuel.
