We have had a problem with the reporting of the logger charge – it doesn’t necessarily mean that the logger isn’t charged. If the LED at the top right of the logger is showing green when connected to a charger, then the battery is fully charged, regardless of what is reported on the screen. If you discharge the battery fully (i.e. by leaving the logger turned on), then when you recharge it, it should be realigned to report correctly.We are looking for a solution to this. If, however, you are not getting the green light, then there is another problem.
There are two reason why this could happen: the software might have been set to "align to strokes" or it could be that no strokes have been taken.
There are two reason why this could happen: the software might have been set to "align to strokes" or it could be that there is no stroke-by-stroke data (see above).
If the boat motion sensor wasn't logged in the session that will possibly be the reason since without the boat motion sensor, the logger itself is not able to understand what a stroke is. Hopefully installing it would solve your problem.
There might be some problems with communications or power. First of all, reduce the system down to minimum (e.g. 1 junction box + sensor). Then build up until problems start appearing. You could also try moving the cables gently whilst viewing data on logger – see if there is an intermittent connection.
