Dear Richard,
On the 3rd of January I randomly changed the coordinates to see if this would mitigate the problem, but it didn’t help. This is why there is an elevation of 253 m in the log.
I am aware of a slight offset in the coordinates. This is a different issue though. Our instrument in still show at previous location (central Slovenia) in EQ Locator, whereas StationView shows the correct one (45.8631° LAT, 15.4625° LON, 153 m, eastern Slovenia). Taking the offset into account, the coordinates you see are therefore correct.
If the problem persists, we will have to replace the instrument with another one before the presentation at the school where this instrument is installed and try to solve this problem later otherwise the EQ Locator will compute wrong location during the demonstration.
Do you think flashing the instrument would help? Do you have access to the log files? If not, I can send you the files.
Best regards,
Gregor
