We've just installed 3 new DLs here on the Isle of Wight UK and unfortunately have had problems with 2 of them.
We followed the manual's instructions to the letter, charging the supercap overnight and then selecting 1 reading on the hour every hour, attaching battery pack etc. The Header basic details were also set with Timezone and location etc.
Returning to the meters a week later we found neither had made any readings although the devices appeared to be operating normally.
Testing back at base showed them both working fine when shorter time periods were set eg every 5 minutes 1/12.
I'm not sure what to do next as it is an inconvenience to keep visiting site just to check operation. Are we missing something?
