Meopta ; remise à zéro des tourelles

[clochka]

Bonjour,
Comment faire pour remettre à zéro les tourelles d'une lunette Meopta ZD 6-24X56, après réglage à 100m par exemple?
Merci de votre aide

Hold the dial knob (pos. 1) so that it cannot turn
- By turning it counterclockwise, loosen the central
cross-head locking bolt of the turret (pos. 2).
- Set the dial to the required value against the vertical
mark (most typically to “0” (pos. 3) On the elevation
adjustment turret and against the horizontal mark
on the windage adjustment turret (pos. 4).
- Tighten central locking bolt (by turning it clockwise).
