Instrument Self Test
Just like when the instrument is powered ON, during
the Self Test the microcontroller interrogates the
system electronics.
To complete the Self Test:
1. Press the button repeatedly until the
screen display looks similar to Figure #28.
2. Press the TRIGGER to complete the Self
Test. Figure #29 shows an example of all
tests proving positive.
 If all tests do not prove positive, the
appropriate error code will appear in
the upper display (page 16).

If the instrument fails the Self Test:
1. Press the button to power OFF the TruSpeed.
2. Press the button to once again power ON the
TruSpeed and repeat the Self Test.
3. Contact LTI if the error repeats and you need assistance.
See the inside front cover for LTI contact information.
