Recording measured data to file
If data recording is active, the GSV-2MSD-DI creates directories on the SD card, which
contain the measured data files.
The directory name is created from the current date, depending on the directory mode
setting. A new directory is created every month in the initial state, with the name:
G20JJ_MM, for example in November 2012 this would be "G2012_11".
The name of the files within it are then formed based on the day and time, i.e.:
DDHHMMSS.TXT. For example, if a file is created on 14.11.2012 at 14:41:39, then the
directory name is as above and the file name:
14144139.TXT
The files are written in ASCII text format. Each measured value creates a line that is
terminated with <LF> and <CR>. Depending on the line settings, each line begins with the
time stamp consisting of date, time and fractions of seconds, then the measured value and
the unit. The default setting for lines is as follows (first line of the example above):
12/11/14,14:41:39.27669 -0.0011 mV/V
12/11/14,14:41:39.37669 -0.0011 mV/V
The date format satisfies the big-endian convention, i.e.
JJ/MM/DD
Date and time are separated by comma. The time format is
HH:MM:SS.bbbbb
whereby the 5-digit fractions of seconds bbbbb, interpreted as a whole number, indicate
10µs steps. In the example above, the data rate of the measuring amplifier is set to 10
measured values/seconds ( ( 37669 - 27669) * 10µs = 100ms = 1/10 s).
Time stamp and measured value are separated with the tab character (‘/t’). Measured value
and unit are separated with a space.
The default setting for the maximum number of lines (i.e. displayed measured values) in a
file is 32,000. As soon as this number is reached, a new file is opened.
In the “onOK” recording mode, whereby recording are only made by pressing the OK button,
the data sets (continuous lines during a recording) are written in the same file. After

For synchronisation reasons, there can be small deviations in the fractions of the time steps.
