You have the following options from the Driver ID Code Entry
Screen:
❏ Enter a Driver ID Code
The flashing digit in the code is the active
digit. Press and release PLUS or MINUS to cycle
forward or backward through the available
entries for the active digit (0 to 9). To change
the digit which is active, press and release SET/
CLEAR. Each time you press SET/CLEAR, the
next digit become active.
❏ Log Out
To “log out” press and hold SET/CLEAR for 2
seconds, until the code resets to 0000. As soon
as a driver logs out, the current trip is ended
and data for that trip stored in the Trip 500AL’s
memory. Note that you may not log out when
the vehicle is in motion.
Driver Performance Score Screen
The Trip 500AL has a unique driver performance scoring sys-
tem that can quickly give you an indicator of how a particular
driver is driving, or a vehicle being driven. The score gives a
rough estimate of the number of time limits are violated per
1000 miles driven. The amount of time it takes to calculate the
score depends on how many trips are currently stored in mem-
ory; it can take as much as 45 seconds.
To calculate the score, the unit assigns 1 point for every accel-
eration and deceleration count, and 1 point for every minute
spent driving over the set speed limit (0.1 points per 6 sec-
onds). The total is then compared to the actual number of
miles driven and adjusted for 1000 miles.
For example, if a driver has 5 deceleration counts, 1 accelera-
tion count, 90 seconds spent over the set speed limit, and 500
total miles driven, the performance score would be 15:
