z Projection distance formulas
z Formules de distance de projection
If you are using a projection screen size not listed in these Operating Instructions, measure the diagonal screen
size SD (m). Then use the calculation methods provided to determine projection distance (L1) and the distance
from the top of the projector to the bottom edge of the screen (A1).
Establishing dimensions L1 and A1 allows you to calculate all other dimensions.
Note that the values obtained in the following calculations are approximations.
If you want to calculate the projection distance with projected image size SD (unit: inch) by substituting, please
assign 0.0254 times to the SD value.
Si vous utilisez une taille d'écran de projection n'apparaissant pas dans la liste de ce mode d'emploi, mesurez la
taille de l'écran en diagonale SD (m). Utilisez ensuite les méthodes de calcul fournies pour déterminer la distance
de projection (L1) et la distance du sommet du projecteur au bord inférieur de l'écran (A1).
Établir les dimensions L1 et A1 vous permet de calculer toutes les autres dimensions.
Notez que les valeurs obtenues dans les calculs suivants sont des approximations.
Si vous voulez calculer la distance de projection avec des images de taille SD (unité : pouce) par substitution,
veuillez ajouter 0,0254 fois à la valeur SD.
