General Information 1-5
1.6 Max acquisition time
The device can measure and save data for a long period of time. The total
time depends on the storing rate, number of frequency bands.
The internal memory can be read at every new data transfer to the central
unit, at set times or by remote control. Moreover, when the memory is full,
the new data are overwritten on the oldest to ensure availability of the data
for the most recent measurement period.
Settings can be made and the devices can be queried via SMS, serial
connection, Ethernet, GSM or line modem, FTP communication through
FTP server. The following table describes the different possibilities.
