DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a test apparatus, and more particularly to a test apparatus applicable to various handheld devices. [Prior Art] The handheld electronic devices that are seen often include a number of attachment functions, such as digital camera functions or global positioning functions, and even the function of receiving television signals is beginning to appear on the hand #electronic device. When the handheld electronic device has these additional functions, it means that more integrated circuits are included on the motherboard to perform various analog and digital conversions. However, for a handheld electronic device, the increase in function is often accompanied by a decrease in the number of hours of use per unit time, especially when the handheld electronic device is in a standby state, and the leakage current generated by the motherboard is often battery consumption. The main reason. However, when the motherboard is assembled into a finished product, the current consumption measurement is limited by the difference between the mechanism housing and the battery signal source pin. 'The exclusive test must be customized according to different models. The fixture can be used to measure the current consumption of the handheld electronic device without disassembling the case. However, when the standby time of a handheld electronic device suddenly becomes shorter or the power consumption of the battery is abnormal, it is necessary for a maintenance engineer to determine that the abnormal situation is caused by damage to the battery itself, or This is caused by an increase in leakage current of the motherboard of the electronic device. 12479〇〇 Under the consideration of maintenance cost and time, Widdy and 卞丨 工程师 engineers generally perform the current consumption test of the main board first, and then compare the results to perform the battery charging and discharging test. However, 'this day's handheld devices are new, and the life cycle of a single product is reduced. If it is only for individual products: different chassis design, it is not necessary to cost a new test fixture. The test fixture design also needs _, and may also indirectly cause delays in the product launch schedule. To solve the above
