Field Mill Selector
Select the field mill for which you would like to configure data logging.
Enable Data Logging Checkbox
Check the Enable Data Logging checkbox if you would like field mill data to be logged to the hard
drive for the field mill selected in the selection box above. Logged data is viewable using the
EFMView Electric Field Mill Data Viewer. Select File…Open… on the main menu to view the data
file. Logging data will consume approximately 1.3 megabytes of hard disk space per field mill per
day.
Data files have a filename consisting of the field mill name, the file date, and a efm suffix. For
example: “Shop Roof-03252004.efm”. Data files are comma delimited ASCII text files allowing the
files to be loaded into spreadsheets or other third party software.

When the High Resolution box is checked, it will store the EFM-100 data 20 times per second.
Leaving it unchecked will store the data 2 times per second. Please note when this option is enabled,
it will also increase the file size.
Logfile Location
This is the directory where the data files are stored. Click on the Open icon to browse for the
directory.
