EM50G CELLULAR COMMUNICATION
If the Em50G Cellular connection quality is poor, try moving your logger a short distance to
improve the signal strength. Also, consider elevating the antenna by elevating the logger or
using an antenna extension cable to improve signal strength. In some cases it is necessary to
use directional antennas to obtain a sufficient cellular signal. Please contact METER for help
choosing the correct antenna for cellular frequencies at yourlocation.
The Communication Test is checking both the cellular signal strength and the connection
to the METER Data Service. If the Data Service is temporarily unavailable due to Internet
problems, the connection quality reports a failure even if you have strong cellular signal.
If your cellular signal strength is good (above 12'), then it is reasonable to expect good
connection quality once the Em50G can re-connect to the METER Data Service.
NOTE: The measurement data collected by your Em50G is automatically queued for the next successful connection to
the METER Data Service. Short term cellular or Internet outages do not impact the integrity and continuity of data.
5.6 DOWNLOADING DATA
You have two options for downloading the Em50G sensor measurement data.
5.6.1 DIRECT DOWNLOAD
Like all Em50 loggers, the Em50G stores more than 36,800 sensor readings for each of the
five sensor ports. You can use any ECH2O system software to directly connect to the logger
for data download. Your data are always safely stored in nonvolatile memory as a backup in
the unlikely event of data loss on your computer. For downloading instructions when directly
connected, see Section4.2.
5.6.2 INTERNET DOWNLOADING
The Em50G and METER Data Service make downloading your measurement data over the
Internet convenient and easy. Use ZENTRA Cloud to remotely access Em50G data.
NOTE: ECH20 Utility does not connect to the METER Data Service for downloading data over the internet.
