3-2 5975996 BARCOGRAPHICS 808s 241197
Where to install the projector ?
To indicate a correct installation position it is necessary to know :
The distance from projector to ceiling in case of Ceiling mounted
or the distance from projector to floor in case of Table mounted;
The distance from projector to screen.
To find the correct position for the BARCOGRAPHICS 808s, equipped
with HD8 lenses, use the following formulas:
Install the projector water levelled in both directions
Install the projector perpendicular to the screen
PD[inch] = 1.269 x SW[inch] + 13.54
A[inch] = 0.12 x SW[inch] - 11.11
In metric :
In inch :
PD[m] = 1.269 x SW[m] + 0.344
A[cm] = 12 x SW[m] - 28.2
Abbreviations used in the calculations and the drawings :
B = Distance between ceiling and top of the screen (Ceiling mounted)
or distance between floor and bottom of the screen (Table
mounted).
A = Correction Value, extra value to be added to B to obtain the
correct installation position (In some cases the A value can be
negative).
CD = Total distance between projector and ceiling (Ceiling mounted)
or total distance between projector and floor (Table mounted).
CD = A + B.
Ceiling Mounted : when the result is negative, enlarge the
distance between ceiling and top of the screen, mount screen
lower, until CD becomes zero or positive.
Table Mounted : when the result is negative, enlarge the
distance between floor and bottom of the screen, mount
screen higher, until CD becomes zero or positive.
SW= Screen width.
PD = Perpendicular distance between screen and projector's mount.
To obtain the right values, you can make use of the new option
included in the Installation Adjustment Mode to let the projector
calculate the parameters automatically. Please refer to Chapter 8 for
details.
