1. An applicator assembly for applying at least a portion of an analyte monitor, the applicator assembly comprising:
a frame having a first end, a second end, a longitudinal axis extending between the first and second ends, and an opening at the second end;
a resilient member positioned at least partially in the frame and having at least a first portion fixed relative to the frame and a second portion movable relative to the frame in a direction substantially parallel to the longitudinal axis;
a needle movable together with the second portion of the resilient member; and
a cap engageable with the frame to cover at least part of the opening;
wherein when the cap is connected to the frame at a first configuration, the second portion of the resilient member is at a first axial position relative to the frame, and the cap is restricted from separating from the frame;
wherein the cap is adjustable from the first configuration to a second configuration to increase a bias on the resilient member and to move the second portion of the resilient member to a second axial position relative to the frame that is farther from the opening;
wherein when the cap is at the second configuration, the cap is separable from the frame, while the second portion of the resilient member is configured to be held at the second axial position relative to the frame; and
wherein the hold on the second portion of the resilient member is releasable, such that the bias on the resilient member advances the second portion of the resilient member and the needle towards the opening to a position where at least a tip of the needle extends axially out of the opening.
