Error Codes
The table below lists and explains each of the possible error codes.
**See inside front cover for LTI contact information.
RFI Considerations
The TruSpeed does not display a specific error message indicating the presence of
radio frequency interference (RFI). The instrument's electronics have been
designed for optimum RFI immunity. If RFI is present, the instrument displays an
error code. The exact code depends on the level and nature of the RFI.
Code Explanation
E 01 Measurement Error - the target was out of range or was too
close.
E 02 Measurement Error - insufficient data. The unit does not have
enough data to measure speed.
Possible Cause:
early release of the TRIGGER or time-out.
E 03 Measurement Error - unstable targeting. Data is not stable
enough to measure speed.
Possible Causes:
poor aiming or panning off the target.
Measurement Error - low level of interference from a light
source such as a xenon headlight.
E 07 Jam Detect - high level of interference from a light source
such as a xenon headlight.
E 52 Temperature too cold. Stop operation.
E 53 Temperature too hot. Stop operation.
E 55 E57
E 56 E58
