The Reaction Tester Screen
Pro Mode Screen 5
This screen allows you to test your reaction time
using the push-buttons mounted in the vehicle. When this
screen is first displayed, everything on the screen is turned
on at the same time. This is a quick way to check for full
functionality of the display. To practice, press and hold
down the push-button connected to the P.B. 1 terminal. If
the Mega 475 is in Push-button Mode 5, press the button
connected to P.B. 2. The screen will go blank. Then when
the screen displays eights on the screen, release the button or
for Push-button Mode 5 press the button connected to P.B. 1.
The Mega 475 will now display your reaction time. Keep in
mind that the reaction time does not directly correlate to the
Delay time used on the Pro screen. This is because the
Reaction Tester does not take into account the vehicle’s roll
out time.
NOTE: While using the Driver’s Reaction Tester, the
Transbrake solenoid will not be activated. This is to prevent
any damage to the solenoid from over-heating.
Reaction Time (Top Line)
This is your current reaction time while practicing.
Average (2
nd
Line)
This is your average reaction time this session. The
Clear key can be used to clear the Average time on the
Driver’s Reaction Tester Screen.
Note: After 30 seconds of non-use the Mega 475 will
automatically return to the Dial-In and Delay Screen.
Press the SET UP key to go to the Replay Tach
screen.
