Claim:
1. A handler apparatus that conveys a device under test to a test socket, comprising: an actuator that, prior to fitting of a device holder holding the device under test to the test socket, fits the device holder, and adjusts a position of the device under test on the device holder; an actuator adjusting section that adjusts an amount of driving of the actuator by causing the actuator to fit an actuator fitting unit; an actuator image-capturing section that captures an image of the actuator; and an actuator position detecting section that detects a distance and a direction in which the actuator moves, based on an image capturing result of the actuator captured by the actuator image-capturing section, wherein the actuator adjusting section drives the actuator in a state fitting the actuator fitting unit, and adjusts an amount of driving based on a distance and a direction in which the actuator actually moved.
