TR-INR
Programming and Use
Inertia Sensor giving
false readings
1.
When first powered up, the TR-INR is in the Acceleration display mode and either of the two
buttons can be used to cycle through the real time and peak recorded acceleration values from the
sensor. The three small lamps at the top of the display are lit solid when viewing the live X, Y,
and V acceleration. The lamps flash when viewing the corresponding peak recorded acceleration
values.
If the Inertia / G sensor is producing false positives, it may be that the sensitivity
need to be adjusted.

2.
To put the sensor into the program mode, hold both buttons down for about 2 seconds
and the display will show a two-digit value, followed by a ‘P’ to signify program mode.
The three lamps at the top of the display signify X, Y or V thresholds.
Programming Mode
3.
To change the value of the threshold, press and release both buttons. The top decimal
will start to flash indicating that the threshold value can be changed up or down using
the buttons. When the desired threshold is reached, press both buttons again to store
the value.
4.
The up/down button may now be used to cycle through the various program options, as
listed below.
x.xP X Axis Threshold - y.
yP Y Axis Threshold - v.v
P Vector Threshold
-
clr Clear Peak values from memory
-
CAL Calibrate the sensor
-
E P Exit Programming mode and return to live display.
5.
The ‘clr’ function is executed by pressing and releasing both buttons when ‘clr’ is
displayed. When successful, the small lamps above the characters will light.
6.
The ‘CAL’ function allows the unit to be calibrated for zero G display. This should only
be done when the unit is in a horizontal position (as close to level as possible). The
Calibration should be done after the unit is mounted in the vehicle. Press and release
both buttons simultaneously to calibrate the unit. The small lamps above the characters
will light when complete.
