Troubleshooting guide

4. Clear the logger
In the unlucky event that none of the above suggestions cures the problem then reluctantly the one last ploy
that can be tried is to clear the logger. Please remember that once the logger has been cleared there is then
no way of ever recovering the deleted data from the logger. The suggested way of doing so is to use the
‘Setup | Set Archive Interval’ option from the main Weatherlink menu. This is a 2-step process: you first
change the archive interval away from your preferred interval. The software warns you that it is about to
clear the archive memory, which you need to OK. When this step is complete you then repeat the process
and change the interval back to your preferred value.
5. No solution can be found
If even clearing the logger fails to fix the problem then this could be one of the rare instances where the
logger has become faulty. Please contact your dealer for support in line with the notes on support provision.
Recurrent archive download problems
If archive download issues start to happen on a recurrent or semi-regular basis then the problem clearly
needs further investigation. There are, broadly, four types of cause that can interfere with archive
downloads:
• A logger that’s loose on its pins or where the USB cable is taut and repeatedly pulling on the logger
so as to loosen it;
• Where the console is run using an AC mains adapter, but the mains supply is very noisy;
• Sources of wireless interference near to the console or USB cable;
• Potential hard drive issues on the computer, e.g. a failing drive;
This isn’t an exhaustive list but covers the main causes. The loose logger possibility is obviously easy to
check out.
A noisy AC mains supply transmits noise and spikes into the console/logger circuitry and hence can cause
data corruption. The noise might arise from the AC supply at that location being inherently noisy eg in a
commercial premises with heavy machinery around or at the end of a long rural supply line. Or there may be
noise-generating equipment such as fluorescent lights plugged into the same electrical ring as the console
adapter.
Either way, the simplest check is to completely unplug the AC mains adapter and run the console on internal
battery power alone – this should completely isolate the console/logger from the mains supply. With the
USB or serial loggers, the console should still run for 6-9 months on a new set of good quality batteries. (NB
This won’t work for the 6555 IP logger, which does require a mains supply.) If running on batteries alone
