Diagnostics
TID PARAMETERS
These values are used when performing a Target ID (TID). These preferences are found in the CSR Prefer-
ences by clicking on the TID Preferences tab.
• Measurement Angle (Default 90) - Total rota-
tion of the target from the forward position
back.
• Forward Bias Angle (Default 25) - Maximum
amount of forward rotation for TID.
• Wobble tolerance (Default 10) - The maxi-
mum amount of wobble during TID.
• Maximum Claw Change (Default 2.0) -
Maximum amount of claw change before
software flags errors during TID.
• TID Stability Count (Default 5) - Minimum
amount of consecutive snapshots of the
target before the unit identifies it as a valid
target.
• Reset Tolerances - Resets the unit back to manufacture defaults.
COMMAND PARAMETERS
Click on the Parameters Preferences tab to access and view Command Preferences. The “CSR Edited”
radio button must be selected to view and edit these parameters. Click on
<OK>
to save changes and exit.
• Positioning Stability Count (Default 5) - How many planes the unit must acquire in sequence before
measurements are displayed.
• Caster Stability Count (Default 5) - How
many planes the unit must acquire in se-
quence during caster sweeps to display the
measurement. Note: The more it is, the
more repeatable the measurements.
• Linear Stability Tolerance (Default .10) -
Distance Measurement. Measures the
height of the target and must be constant to
acquire a target.
• Angular Stability Tolerance (Default .05) -
Angle of the target. Measures the width of
the target and must be constant to acquire a
target.
• Positioning Angle (Default 40) - How many
degrees the target must rollback before
acquiring a reading.
• Positioning Angle Tolerance (Default 10) - Minimum / Maximum for “Positioning Angle”.
• Centering Tolerance (Default .25) - The maximum a target can be turned before the unit will ask the
operator to steer the wheels straight ahead. Steering angle during centering.
• Positioning Wobble Tolerance (Default .10) - Maximum angle that a target can move during positioning
before wheel wobble occurs.
• Caster Roll Tolerance (Default .30) - Maximum angle that a target can roll during caster sweep before
wheel roll occurs.
• Smoothing Factor (Default .7) - Smooths out display meters. Note: Keeps meters from jumping.
• Dropout ( 10ms units) (Default 350) - Amount of time it takes to drop a target when a target is blocked.
• Front First Threshold (Default 1.3º) - sets the value at which the Adjust Front First Indicator Icon ap-
pears on any of the rear reading screens. (See operator manual for details)
• AC400 Runout Angle Tolerance (0.5 - 5.0) How much the arms vary from the axis of rotation.
• AC400 Unequal Arm Tolerance (0.1 - 0.5) How much difference in length the clamps are to each other.

RUNNING IN THE EXTREME WEATHER MODE CHANGES DEFAULTS.
