EM50
Follow steps 1 through 5 to download data.
1. Use the USB cable to connect the Em50 to your computer.
2. Choose "Direct on" the appropriate COM port from the Connect Via drop-down list and
press the "Connect" button. If you encounter connection errors, please see Section8 or
the ECH20 Utility Help File.
3. Once connected to an Em50, either click the Download button on the toolbar, or go to the
Data Menu and select a download option as described above.
4. When saving data, the File > Save dialog suggests a name based on the connected logger
name and the time and date. However, you can enter any name by typing it into the "File
name" field.
5. Choose the file format (Common formats include .xls, .csv, or .dxd) you prefer then click
Save. ECH20 Utility then downloads the data and creates the file.
ECH20 Utility can save your data in several different file formats.
Excel Workbook File (.xls): Converts the raw downloaded measurement data into
engineering values appropriate for each sensor type. The converted data saves to sheet 1 of
the workbook and raw data saves to sheet 2. You can use the raw measurement data to apply
custom calibration to your sensor data.
DataTrac3 Data File (.dxd): Saves the file in a format that DataTrac3 can import. Each .dxd
file contains information about the ECH
2
O logger settings, identity, and status along with the
raw data for each sensor.
Processed Data Text File (.txt): Converts the raw downloaded data into engineering values
appropriate for each sensor type. Data are saved as a tab delimited text file.
Raw Data (.csv): Saves the raw data in the form downloaded from the logger.
NOTE: The DataTrac3 file format (.dxd) is a useful way to store data for later manipulation. Each .dxd file contains
information about the ECH
2
O logger settings, identity, and status along with the raw data for each sensor. ECH20 Utility
can process a .dxd file into an Excel file or a processed text file. This allows you to process your raw data again with
different settings or file formats.
4.2.3 OTHER DATA DOWNLOAD OPTIONS
METER designed the Em50R to be part of a wireless sensor network. In this mode, Em50R
transmits measurement data to a data station. You can then download the measurement
data from all the Em50R loggers in your network from one location. The communication
protocol also confirms delivery of the data and continues to request data until it receives the
complete data package. See Section6 for more information on setting up logger networks.
We designed the Em50G logger to upload your measurement data to METER Data Service
using the cellular network. This makes it easy for you to use the Internet to download your
measurement data from anywhere in the world. Please see Section5 for more information.
NOTE: ECH20 Utility uses the default conversion equation for each sensor when converting raw data to processed
data. For more information about the default conversion equations, please see your logger or sensor manual.
