    3.3 System settings (SYSTEM) (1) Baud Rate: You may set up a transmission speed of RS-232 to 9600, 19200, 38400, 57600, or 115200. Please note that this needs to be aligned with the speed at the control end. (2) Upload Data: Automatically uploads the test results.Available options include OFF, RS-232, FLASH and BOTH.

    3.4 Function (FUNC) (1) Key Lock: Keyboard lock prevents the test conditions from changes by unexpected user operation. Once it is on, users can start and stop the test without changing any settings. To unlock the keyboard, input the password you set earlier. To change the password, please refer to the system setup steps given earlier.

It deducts the leak current by the jig in advance and displays the actual leak current of the DUT with the equation “measurement readings = actual measurement less reset value”.

  • Page 20: Specification Setup2 (Setup)

    3.6 Specification setup2 (SETUP) (1) OPEN: Open circuit detection sensitivity. Poor connection of the high voltage test wire to the DUT may lead to a lower measurement current and invalid qualified product results in the voltage test. Once this function is enabled (with non-zero settings) your machine will measure the DUT's capacitance with low voltage for about 200ms before the high voltage test begins.
  • Page 21 its settings must be lower than the latter. (3) High voltage output time and results determination timing: See the diagrams below for the results determination the timing after the TEST key is pressed by the user. Please note that in the IR delay and ascending time, no upper and lower limit will be determined while only the upper limit will be determined in the ascending time of the ACW and DCW modes.
