Computerscales XLi Tablet Instructions
Quick Start
This tablet uses the Android® operating system. Many functions are similar to 'Smart phones' and it uses a
touch screen to access.
ON: Push and hold for 3 secons to launch the operating system (OS) - about 15 seconds.
Tap the app icon on the Home Page (first up) to launch the "app" - COMPUTERSCALES
XLi. This takes about 5 seconds.
Turn pads on: The greedn LED will be steady until the LF link is established between the pads and the
tablet (usually less than 10 seconds). Then the green LEDs will flash. "No Data"indicates that the tablet is
not receiving weights. Be sure pads are on and LEDs are flashing.
Zero: Tap BEFORE putting car on scales. DON'T zero AFTER car is on scales.
"Sleep" Mode: To conserve battery power the display goes dark after 30 minutes. To restore push ON
once (don't hold as when turning tablet on). To manually put into Sleep Mode (save power) push ON
once (don't hold). Display goes dark. To restore display push ON again (don't hold).
To shut system down: (different from "Sleep") - Push & HOLD ON for 3 seconds. Display changes.
Tap "Power Off", then tap "OK". If you don't do this the tablet battery may be low the next time. Be
sure to turn off all 4 pads too.
Memory: Tap arrows (< & >) to select memory number (1-50, center bottom). Tap Save in Memory to
save current weights. Memory weights are shown under current weights, indicated by M.
Rotate wheel weights on display: Tap on roof of car icon. Weights rotate in 90º increments. See below
for more information.
Recharge tablet / replace pad batteries: Connect charger at bottom center of the tablet. Recharge takes
5-6 hours. Replace pad batteries with 3 "AA" alkaline. Pad batteries last 50-60 hours, tablet 8-10 hours.
Customize Partial %s: Swipe screen R to L. Tap Start Over and select.
Simple Troubleshooting: If you have any connection problems (NO DATA on display) first re-boot the
LF pad (off, then back on). If this does not correct the issue re-boot the app (this takes just a few seconds).
Check all batteries - pads and tablet (no need to change unless they are low - it doesn't help)
Here are the details on the operation of the various features. Use as many or as few as you want.
Different displays: Accessed by swiping your fingertip across the display, side to side.
Bright Sunlight Mode: Swipe your finger left-to-right. This is B&W maximum contrast to allow
easier reading in very bright conditions. Swipe back right-to-left to get back to the main screen.
Setup Mode: Swipe your finger from right-to-left. Here you can make changes to suit your
preferences. To change the partial %s displayed first tap Start Over at the top of the list. (For
changes on small buttons consider using the included stylus if you have difficulty.) Tap your
preferences in the order you want them displayed. The order will be shown at the right. You can
even add a blank line. Select as many as you want. Up to five will be shown all the time on the
main screen but you can easily access others chosen by scrolling the list up or down. While in the
Setup Mode you can also change other settings - for example partial % - .1% or .01%, the car icon,
weight units, etc. Here is where you can convert to METRIC. Select your preference. These will
stay until you change them again. When done swipe to the main screen, close the "app", then re-
open it again.
(Tap at bottom right - this takes you to the Home Page and automatically closes the "app" -
tap the icon to re-start).
"Car" icon on screen: There are 4 standard choices: Stock Car, Indy/F1, Modified and Kart. You
can also personalize your tablet and have a picture of your car as the icon. Please call the factory
for details.
DO NOT alter any settings in the top black section of the setup screen. This involves pairing the
pads to the tablet.
Rotate the car icon and wheel weights: The default wheel weight display is the traditional one. If
you are standing in a different location you can rotate the car icon and all 4 wheel weights in 90º
increments for more convenient viewing. Simply tap on the car icon to rotate. This will reset to the
default layout if the tablet is turned off. The tablet itself can be rotated and all information with be
reformatted - horizontal ('Landscape') or vertical ('Portrait').
Tablet 'Sleep Mode': To extend battery life the tablet is set to go into Sleep Mode automatically
after 30 minutes (screen goes dark). To bring back push the ON button once (don't hold). All
weights and % are kept. This is almost instantaneous.
To manually put tablet into 'Sleep Mode': Push the ON button (don't hold). The screen will go
dark. Bring back the same way as above.
When you are done be sure to POWER OFF the tablet (different than Sleep). Push ON and
HOLD 3 seconds. Screen changes. Tap Power OFF, then tap OK. This should be done when you
are not going to use the scales for several hours or longer. If not done the tablet battery may be low
or dead next time you use the system. Also turn off all 4 pads.
Low Battery indication: Pad battery indication is on the black pad module - the green LED. It
is also shown on the tablet by a green dot under each of the 4 wheel weights. As batteries get low
this changes to orange, then eventually to red. Replace with 3 quality alkaline "AA" batteries. Pad
battery access is on the end opposite the black module. Remove the 2 Phillips screws on the bottom
of the pad to remove the battery holder. Pad batteries last 50-60 hours.
For Tablet battery indication go to the Home Page by tapping at bottom right. Battery life
will be shown at the top right as a bar graph and %. Put in Sleep Mode when not needed. Be sure to
Power Off tablet when done. Also shut off all 4 pads.
NOTE: If there is no Low Battery indication on the pad or tablet screen changing the pad batteries
is not necessary.
Notes: The LR, RR, & RF pads communicate only with the LF pad which sends all 4 wheel weights to the
tablet. If you need to use just one pad it MUST be the LF. The LF pad MUST be on for the system to
function.
A screen saver has been pre-installed. This helps protect the screen from scratches. Replace when needed.
Warranty Policy on Tablet Scale Systems
Tablets are warrantied for a period of 1 year and the pads for 2 years from the date of retail/consumer sale
(not from the date of manufacturer’s sale to the dealer as some other scale manufacturers do). We will
handle any tablet manufacturer’s warranty for you since the repaired or replaced tablet needs to be
configured, linked to the pad modules, and calibrated. (The tablet is a part of an overall interconnected
system.)
For warranty (or non-warranty) work please return the tablet and all 4 pad modules with battery packs.
Please do not send partial systems as we will not be able to complete the service properly. It is not
necessary to send the entire pad(s), just the modules. This helps keep shipping costs down. All our load
cells are matched. There are rare exceptions to this. If you suspect that the actual load cell is causing
problems please contact the factory service department for instructions on how to check this.
The modules can be easily removed from the pads by removing the 4 Phillips head screws on the bottom of
the pads, 2 on each end. Slide the black module out and disconnect the load cell (large silver knurled nut).
Slide the battery pack completely out of the pad. We need all 4 modules and the tablet to perform proper
service. Please pack everything very carefully so they are not damaged in transit, specially the tablet
display. It is best to leave it in the protective folio. We cannot warranty a tablet and/or module(s) that have
been damage in transit.
To return a system for service please contact the factory for an RMA tracking number. This helps us get
your service done as quickly and efficiently as possible. PLEASE DO NOT SEND SYSTEMS BACK
WITHOUT THIS RMA NUMBER. It should be clearly marked on the outside of the box and inside
include a quick note with your name, phone number, and the RMA number again.
If you choose to send the entire system with pads there will be a modest additional charge plus additional
return freight. If you send the tablet and modules only for warranty service and need them returned faster
than ground service we ask that you pay only the difference in cost.
IMPORTANT NOTE: The tablets included are fully functional tablets using the Android® OS. They will
support many other apps besides the one we supply. However there is always a potential conflict between
apps over which we have no control. We will warranty and support both hardware and software (our app)
on these systems ONLY if no other app or apps have been installed. If you have trouble after installing
another app we urge you to delete that new app first to see if an app conflict is the problem. We cannot
warranty that this system will function properly with any other apps.
