The present invention generally relates to a weight setting indicator which is used to indicate that an applied force to a tool achieved or exceeded a predetermined amount. In one asepct, a packer actuator (100) for use with a packer is provided. The packer actuator includes a body (105) with a recess (135). The packer actuator further includes a dog assembly (175) disposed in the recess (135) of the body (105). The dog assembly (175) is configured to set the packer when a force is applied to the packer actuator (100). The packer actuator (100) also includes a setting indicator (200) disposed in the recess adjacent an end of the dog assembly (175). The setting indicator (200) is configured to move from a pre-set position to a post-set position when the force is applied to the packer actuator, wherein the setting indicator (200) is plastically deformed in the post-set position. |
