8.0 SELF CALIBRATION
All balancers are carefully calibrated by the manufacturer
and do not require a new calibration, except after many years
of service or in case of replacement of any electronic component.
To recalibrate the machine proceed as follows:
A. Switch the machine off.
B. Mount a wheel with an average size steel rim ( i.e. 14"),
even unbalanced.
C. Press CAL while turning the machine on. Hold the button
for at least 5 sec.
After the lamp test, the displays blink:
[CAL] [Usr] then display [diS] [ 60].
D. Enter the correct wheel data (section 6.1) and press F .
The displays show: [CAL] [ 1 ].
IMPORTANT!
IF THE WHEEL DATA ENTERED ARE NOT CORRECT, A
WRONG CALIBRATION WILL BE MADE AND ALL SUB-
SEQUENT BALANCING READOUTS WILL BE WRONG.
E. Lower the wheel guard to spin the wheel.
While the wheel is cycling the displays show:
[CAL] [ 1 ] and when the wheel stops :
[100] [Add] ([4.00] [Add] in ounces).
The inner plane angular displays are illuminated.
F. Attach 4 oz (100gr) weight on the inner plane at top, when
the angular displays of the inner plane are illuminated. Spin
the wheel. While the wheel is cycling the displays show: [CAL]
[ 2 ] .
G. When the wheel stops the displays show two numbers.
Press the buttons 1 or 2 (Fig. 61) to change the values. Adjust
the numbers to be closest to [100] [0 ] ( [4.00] [ 0 ]).
Press F to confirm.
H. The displays show : [Add] [100] ([Add] [4.00]).
The outer plane angular displays are illuminated.
Remove the 100gr (4 oz) weight from the inner plane and
attach it to the outer plane at top, when the angular displays
of the outer plane are illuminated. Spin the wheel. While the
wheel is cycling the displays show: [CAL] [3].
J. When the wheel stops the displays show two numbers.
Press the buttons 1 or 2 (Fig. 61) to change the values. Adjust
the numbers to be closest to [0 ] [100] ([0 ] [4.00]).
Press F to confirm.
K. The displays show [CAL] [End].
The program switches automatically to Dynamic balancing.
8.1 OUNCE/GRAMS CONVERSION
When the machine is first turned on it is preset to display the
imbalance in grams.
If the display in ounces is desired, press and hold F (#10
Fig. 61) then press GR-OZ (#4 Fig.61).
Repeat the procedure for converting back to grams.
It is possible to check if the machine is preset in grams or
ounces by observing the displays.
If after turning on the machine the displays show
[ 0 ][ 0 ] the machine is preset in grams.
If after turning on the machine displays show
[0.00][ 0.00] the machine is preset in ounces.
8.2 FINE BALANCING MODE
This balancer always measures with the maximum precision
available (1gr or 0.1 oz), however values below 5 gr (0.25
oz) are shown as zero.
Values exceeding 5gr (0.25 oz) are rounded to the amount
of the nearest commercial wheel weight.
Press and hold the button FINE (#7 Fig.61) to display the
residual imbalance below 0.25 oz (5 gr) or in any case the
value of imbalance with 1gr (0.1 oz) resolution .
8.3 RIM DIAMETER IN MILLIMETERS
The rim diameter is normally displayed in inches, however if
the value in millimeters is desired, press button 5 or 6 (Fig.
61) , press and hold F (#10 Fig. 61) then press MM- INCH
(#6 Fig.61).
Repeat the above operation to convert back to inches.
