ECO VSF User’s Guide (VSF) Revision AN 14 Sept. 2011 21
8. Device and Output Files
Each meter is shipped with a CD containing the meter-specific device file, a sample output file,
characterization information, and the applicable user’s guides.
The ECOView host program requires a device file to provide engineering unit outputs for any of
its measurements. Except for the first line in the device file, all lines of information in the device
file that do not conform to one of the descriptor headers will be ignored. Every ECOView device
file has three required elements: Plot Header, Column Count Specification, and Column
Description.
8.1 Plot Header
The first line in the device file is used as the plot header for the ECOView plots.
8.2 Column Count Specification
The Column Count Specification identifies how many columns of data to expect. It follows
the format “Column=n.” The Column Count Specification must be present before any of the
Column Descriptions are listed.
8.3 Column Description
Every column in the ECO meter’s output must have a corresponding Column Description in
the device file. The following notation is used in identifying the elements of each Column
Description.
x = the column number, starting with 1 as the 1
st
column
sc = scale
dc = dark counts: meter output in clean water with optics head taped
mw = measurement wavelength—wavelength used by the sensor for its measurement
dw = display wavelength—display wavelength—wavelength/color range (380–780 nm)
v = measured volts dc (not used on VSF)
Valid Column Descriptions are listed below.
Date=x MM/DD/YY
Time=x HH:MM:SS
N/U=x The column is Not Used
N/U=x The column is Not Used
