1) Why is there a log continuous with a measurement interval and Report Interval tab? Are you expecting to have these reports uploaded to a web site?
The "Log Continuous" feature is for gathering readings from the meter and storing them on to the disk in a specified format.
The "Report Interval" tab is used used to set the SQM into a mode were it sends data out at specified intervals without being requested by the "rx" reading request command. There may be very few reasons to use the "Report Interval" feature unless you have some "Listener" software waiting to hear from the device. If you encounter spurious readings under normal reading conditions, it may be that an undesired Reading Interval has been set.
UDM does not currently upload readings to a web site. At the moment,
Knightware SQM-Reader Pro does this, and our
sqm-le_perl-1.3.zip program can also be modifed to do something similar.
2) Is it ok to leave SQM on all the time?
Yes. The SQM-LU draws very little power, so it will not be a big drain on your system.
Some laptop/notebook computers may put the USB port to sleep in a power-down mode. Settings in the Windows control panel power profile section are used to control this behaviour.
