Test auxiliary device

A test auxiliary device for testing a portable data terminal having a plurality of sensors, the test auxiliary device comprising:

• a base;
• a carrying unit disposed on the base and comprising a carrying platform and a carrying base, the carrying platform being disposed on the carrying base for receiving the portable data terminal, the base forming a first angle with the carrying base and a second angle with the carrying platform, wherein the carrying platform and the carrying base together form a compound slope;
• a driving unit disposed on the base, connected to the carrying unit, and used for driving the carrying unit to move and allowing the carrying platform to move with acceleration and at an angular velocity;
• and
• a controlling unit connected to the portable data terminal, used for receiving sensing values generated by the sensors, respectively, and used for comparing and analyzing the sensing values and sensing reference values stored in the controlling unit.
