Longacre 78290 Digital Caster_Camber Gauge with AccuLevel (version 2) - Manual (Page 2)

OPTIONAL: Setting Caster To .1 O (1/10 O )
1) To set CASTER more precisely using the AccuLevel™ digital readout (instead of the vial)
first turn the wheels 15 O (this is different than when using vial type gauges) to the right when
setting the RF or 15 O left when setting LF. Rotate the gauge until it is level.
2) Turn on the AccuLevel™ and push ZERO to zero degrees at that point (shows 00.0 00.0 00.0 00.0 00.0 O ).
3) Turn wheels back to center and continue to 15 O in the other direction (a total of 30 O ). Again this is
different than when using vial type gauges. The 15 O must be done accuretely. An error of even 1 or
2 O turning will give a noticeable caster error. Consider turnplates for the best accuracy.
4) Rotate gauge to level. Read the digital display and DOUBLE THE NUMBER FOR (TOTAL)
CASTER, accurate to .1
O . For example display reads 1.8 O x 2 = 3.6 O caster.
Using 15 O rather than 20 O wheel turning is sometimes better on race cars. On some front ends
it can be difficult to turn the wheels a full 20 O , which will cause an error in the caster reading.
Gauges are calibrated to use either 15 O or 20 O turning and cannot be interchanged.
AccuLevel™ can be removed and used
for other measurements. Simply slide it out
(it’s held in place with magnets).
Turn on: Push ON/OFF. AccuLevel™ is
ready to use. ABS ABS ABS ABS ABS will appear on the display if
the unit is in Absolute Angle Measurement Mode.
If it does not display
ABS ABS ABS ABS ABS push ZERO.
Zero: The ZERO button is ONLY used to
compare one angle to another. Place
AccuLevel™
on an angled surface and push ZERO. The display will go to 00.0 00.0 00.0 00.0 00.0 and ABS ABS ABS ABS ABS will disappear. Move to
a different surface to compare angles .FOR NORMAL USE ABS ABS ABS ABS ABS MUST BE ON DISPLAY.
Push ZERO again to go back to Absolute Angle Measurement ( ABS ABS ABS ABS ABS )Mode.
To hold reading: Push “HOLD”. The display will show HOLD and flash . When HOLD stops
flashing (approx. 6 sec.) the reading is held on the display.
AccuLevel™ must be head very
steady during this 6 seconds. Push “HOLD” again to go back to absolute reading.
To CALIBRATE: Place AccuLevel™ on a reasonably level table top (does not need to be
perfectly level). Push ON/OFF and hold for 6 seconds and release. Push ON/OFF again and - 1 - - 1 - - 1 - - 1 - - 1 -
appears on the display. Push ZERO. - 1 - - 1 - - 1 - - 1 - - 1 - will begin to flash and in a few seconds - 2 - - 2 - - 2 - - 2 - - 2 - will appear.
Turn unit around 180 O in the same spot and push ZERO again. - 2 - - 2 - - 2 - - 2 - - 2 - will begin to flash and in a few
seconds normal readings will reappear. Calibration is now complete. This takes less than 30 seconds.
