Hunan Next Generation Instrumental T&C Tech. Co., Ltd. 3.4 Installation Instruction N62400 dissipates heat through the built-in fans. When installing, please make sure there is a gap of at least 20cm between N62400 and other objects for air circulation. The power cord is a 3-core wire with grounding protection. Please use a suitable socket for operation. The power cord also matches your local voltage and plug type. If it is not matched, please contact NGI. 3.4.2 Power-on Self Test Before power-on, please make sure the following. 1) The nominal voltage of the AC input socket should be in the...

Hunan Next Generation Instrumental T&C Tech. Co., Ltd. In case of test failure, please record the error information and contact NGI for support. If N62400 cannot be started properly, please refer to the following steps. 1) Check whether the power cord is properly connected. 2) Check whether the power is switched on. 3) Check whether the fuse is burned out.  If yes, please replace it.  Please use the proper fuse.  When replacing, please open the plastic cover at the AC power socket. For more support, please contact NGI. 3.5 Connection 3.5.1 Input Connection Warning: To meet safety...

Hunan Next Generation Instrumental T&C Tech. Co., Ltd. Meanwhile exceeding heating may cause safety accidents. It is recommended to use standard copper wire with bigger diameter and less length to ensure the voltage drop should be less than 0.5V while N62400 is working. Notice: To meet higher slew rate load specification and performance, the inductance of the wire between DUT and N62400 should be less than 5.0^H. 3.5.2 Control Connection At the rear panel, there are terminals for remote sense, external programming input, etc. Figure 7 Control Signal Terminal Table 6 Terminal Definition...

Hunan Next Generation Instrumental T&C Tech. Co., Ltd. 3.5.3 Sense Connection N62400 provides two types of sense: local sense and remote sense. User can select sense mode on the screen under Application on the menu.  Local sense It is used when the load current is not very high.  Remote sense Remote sense is also four-wire sense. When N62400 is working, it will cause a voltage drop in the leads between the DUT and terminals of N62400, which will affect the voltage measurement accuracy of the load. When working under CV, CR and CP mode, to ensure accurate measurement, it is recommended to...
