Hardware Connection
Each set of the alligator clips contain four clips: big red clip, big black clip, small red clip and small black clip. Please note:
Red clips connect to positive electrode of the battery.Black clips connect to negative electrode.And Big clips supply the current.Small clips measure the cell voltage.
For connection of three-electrode test the big red clip connects to positive electrode of the cell while big black one connects to the negative since the big alligator clips help forming the current loop.Small red clip and small black clip are to measure the cell voltage, so they should be connected to the working electrode and reference electrode respectively.
Connect to the computer
LAND Battery Testing systems come with a desktop computer providing RS232 serial communication port (9-pin), which is used to connect the battery test system.
To make connection, use the communication cable (provided with the test system) to connect the RS422 port on the back of the test machine (Figure 1-1 ⑦ or ⑧) with the
RS422communication port in the desktop computer. If there are several testing boxes, use the other port (⑦or ⑧) connected to the next boxes and thus all the boxes can be connected. The computer automatically searches for all the boxes.
If new PCI-E RS232 Serial Adapter Card is installed, make sure the driver is also updated. The user can also use a USB to RS232 Serial Adapter cable. It is not recommended since the USB to RS232 convert cable is not as reliable.
