A method of calibrating and debugging a testing system is provided. First, values of different electrical path segments are calibrated, and parameters of the electrical path segments while being calibrated are saved. After calibration, electrical tests can be processed on a DUT. If the testing system malfunctions, the values of the electrical path segments are calibrated again to compare the current parameters to the previously saved parameters. The component which goes wrong can be found out quickly in this way.

Method of calibrating and debugging testing system

A testing system includes a test machine, a plurality of probe sets, a data input device, a controller, a memory, and a data output device. The test machine has a platform for a DUT to be placed thereon, and a test arm which is movable relative to the platform. The probe sets are provided on the test machine with at least one probe set provided on the test arm to contact the DUT. The data input device is used to input information about the DUT. The controller is electrically connected to the test arm, the probe set on the test arm, and the data input device to move the test arm to a predetermined position according to the inputted information, and to make the probe set contact the DUT for electrical test. The memory saves electrical test result, which is outputted by the data output device.

Testing system and method for testing of electrical connections

A method of operating a testing system is provided, wherein the testing system has a test machine and a probe module, which has a first probe set and a second probe set. One of the first probe set and the second probe set can be connected to the test machine. The method includes the following steps: connect the test machine and the first probe set; calibrate the testing system; abut the first probe set against a DUT to do electrical tests; disconnect the first probe set and the DUT; disconnect the test machine and the first probe set; connect the test machine and the second probe set; calibrate the testing system again; abut the second probe set against the DUT to do electrical tests.

Method of operating testing system

An electrical testing device includes a base having two parallel first rails, a platform provided on the base, a support provided between the first rails, a test arm, a rotary table provided on the test arm, a plurality of holders provided on the rotary table, and a plurality of probe sets respectively provided on the holders. The support has a second rail provided thereon, and is moveable relative to the base and the platform. The test arm is provided on the second rail and above the platform, wherein the test arm is moveable along with the support, and is also movable relative to the support. The rotary table is moveable or rotatable relative to the test arm. The holders are moveable along with the rotary table, and are also moveable or rotatable relative to the rotary table. The probe sets are moveable along with the holders.
