This is a flagship model that arranges probe heads on both the top and bottom, enabling simultaneous in-circuit testing of the front and back of the substrate.

To ensure that electronic devices function correctly, the electronic circuit board within the device must operate normally. The electronic circuit board becomes operational when electronic components are correctly mounted on the printed circuit board (PCB) and power is supplied. The process of contacting a dedicated probe to the electronic circuit board, which has electronic components mounted, and applying minute electrical signals for testing is called In-Circuit Testing (ICT), and the device used for this testing is referred to as an In-Circuit Tester. This method allows for the inspection of "connection reliability between electronic components and the board," "the values of individual mounted electronic components (such as resistors and capacitors)," and "diode polarity," without imposing unnecessary loads on the board itself. It is also known as MDA (Manufacturing Defect Analyzer). Main inspection items include: - Solder shorts and opens - Pattern disconnections - Missing components - Incorrect component values - Reverse insertion of polarized components - Lifted leads of ICs and connectors - Operation confirmation of digital transistors, optocouplers, and Zener diodes - Other simple function tests.
