To recalibrate your HyperPAC™ to a particular drag strip, follow the steps below.
1. Select the Drag Strip program from the HyperPAC™ "Main Menu" and touch
CREATE NEW TEST SESSION.
2. Carefully stage your vehicle as shallow as possible. If you bracket race and
always deep stage, then stage as you would normally. However, since deep
staging is not as precise as shallow staging, your calibration will not be quite as
accurate.
3. Once you have properly staged, touch START TREE. Ignore the track Tree
until after your HyperPAC™ Tree goes "Green." Then , if the track Tree shows a
green light, you may leave. If not, let it turn green and then leave. Don't worry
about either red lights or slow reaction times when doing calibration runs.
Reaction times and red lights do not affect elapsed times or speeds. You have
up to one minute after the HyperPAC™ goes green to leave . If you do not leave
before the HyperPAC™ times out, a "Run Error" screen will be displayed. Touch
OK, then touch STAGE VEHICLE and you will be ready to start the tree again.
NOTE: How many runs do you need for calibration? You can use just one run,
but greater accuracy is achieved if you use as many runs as it takes to get at
least three very consistent timing slips based on the 60-foot times and the 1/8- or
¼-mile elapsed times and speeds. If your car is not very consistent, you may
calibrate using 4, 5 or 6 of your best runs, but 3 is usually enough.
4. After you have 3 or more consistent runs (or one run if that is what you
choose to do) , touch END SESSION and enter the Drag Strip review mode by
touching VIEW SAVED SESSIONS.
5. Go to the session you just completed and select the first run you wish to use for
track calibration.
6. Select the "Review Setup" screen for that run and touch TRACK CALIBRATION.
