Que faire, quand . . .

Probléme

–A l’observation sans lunettes, le point du bouton de mise au point et la flèche sur le gainage (à gauche à côté du bouton de mise au point) sont l’un en face de l’autre, mais l’observation à l’infini manque de netteté.

Cause

Solution/Explication

– Voir ci-contre à droite.

– Le repère (Flèche sur le gaina-

 

ge, à gauche du bouton de mise

 

au point) pour le réglage sur

 

l’infini est valable pour zéro

 

dioptries donc sans différence

 

d’acuité visuelle. Si une com-

 

pensation dioptrique est réglée

 

ou s’il existe pour les deux yeux

 

de l’observateur la même myo-

 

pie ou presbytie, alors la positi-

 

on pour l’infini des symboles se

 

déplace en conséquence.

–Le bouton central de mise au point ne permet pas de faire un tour complet. Dans la fenêtre de contrôle de l’échelle de gra- duation, des repères d’index sont visibles et dans un des tubes de la jumelle la vision est floue.

–Lors du réglage de la netteté, l’étendue de léchelle de gradua- tion a été dépassée d’au moins un demi-tour par une des deux moitiés du bouton moleté, l’échelle a donc été «doublée». La valeur indiquée se trouve en-dehors de l’étendue de mise au point de la jumelle.

–Remettre la jumelle à la positi- on zéro en découplant les deux moitiés du bouton de mise au point et en les tournant à con- tresens l’une par rapport à l’au- tre, jusqu’à ce que la graduati- on se retrouve au centre de la fenêtre. A ce moment, il est de nouveau possible de faire un réglage dioptrique correct.
