What if the battery test systems could not be recognized by the computer?

First, check if the battery test systems could be turned on: Plug it in, and turn on the power switch. Check if there is flashing of the 8 channel indicators. If yes that means the power is on, then go to the next step. Otherwise, contact customer support.

Second, use a different computer to connect to either of the serial ports on the back of the battery tester. Turn on the power. Start the LANDCali program (located at the place Land software was installed). Select Unit From 1 to 256. Click “Connect”. If everything is fine, the tester should be recognized by the program. If it shows abnormal, then click “Advanced” on the lower-left corner, input the “unit No”, and click “Write”. Please note that “I_Range” and “V_Range” are pre-set by the manufacturer and indicated on the label of the tester. (“I_Range”, and “V_Range” are not supposed to be modified by customers.) Turn off the software and the battery tester. Restart.

If the computer failed to connect to the battery tester, there is a problem with the communication ports or cables. Replace one of the cables and re-check. If it shows that “COM could not be opened”, then there is a problem with the setup of the COM of the computer. The serial port on the computer should be fixed first.
