Connect an external DC power supply capable of outputting 0V and 5V be- tween pin 8 (On/Off_In) and 21 (GND) of the analog interface. Other analog input pins should also be connected correctly. The wiring method is shown in the figure below.

  • Page 100: Anti-Reverse Connection Module Function (Optional)

    System-Related Functions Under the load state, the voltage and current setting method are simpler than that under the power state. The user needs to connect an external DC power supply capable of outputting 0V ~ 10V between the voltage setting pin 1 (Vol_ Pro), current setting pin 17 (Cur/Vol_Pro) and ground wire 3/4/5/6 (AGND).
  • Page 101 System-Related Functions Wiring method: Insert one end of the anti-reverse connection module to the DC output terminal and sense terminal of the IT-M3600 rear panel, and connect the other end to the test line of the DUT. Introduction of the wiring method: By default, the DC+/DC- and Sense test lines are not of standard configura- tion during ex-factory.
  • Page 102 System-Related Functions Usage method: After the IT-M3600 instrument is connected to the anti-reverse connection mod- ule, the instrument automatically detects the module connection state; if the connection is succeeded, the SDS module setting in the system menu is de- faulted as Enable, and the anti-reverse connection module is under enabled state.
