Install the software from the disk onto your laptop. There is a couple different programs. LogWorks and LM Programmer.
Plug in the cable and log onto the lc1 using LM programmer.
Click on the analog output 2 tab and check your voltages like already stated. If voltage is set right, the graph will show a perfectly straight ramp from the bottom left corner to the top right.
Also go into the advanced setting and set warm up and default voltages to 5.00v
Where is your lc1 controller located?
And make sure that analog output 2 is the one that's actually connected to the power logger.
