Index: serial number, beginning with 1.
Absolute date/time: date and time when
the measurement/set of measurements
was recorded.
Relative time [s]: elapsed time in sec-
onds, from the beginning of the measure-
ment to the recording of the current meas-
urement/set of measurements.
Save selected data to files: converts the
measurements selected in the left-hand list
into text files (separated by tab charac-
ters). A file name is requested for each
measurement. The preset file names in-
clude date, time, measurement values and
sampling rate and can be adopted without
any changes.
Quit exits the program.
Device Set-up
Vdc/Vac/(Idc/Iac): selects the measuring
mode for the aforementioned analogue in-
put (Vdc: DC voltage/Vac: AC voltage/Idc:
DC current/Iac: AC current).
Range slider (200mV-20V/200mA-2A):
selects the measurement range for the
above-mentioned analogue input.
Auto Range: if this control box is acti-
vated, the measuring range is automati-
cally adjusted by the device during the
measurement.
Store: determines whether data from the
aforementioned input should be stored.
Sampling rate slider: this sets the sam-
pling rate for the measurements. Fre-
quency is displayed in the field f=, and the
corresponding cycle duration is displayed
in the field T=.
Apply settings: writes the selected set-
tings to the device.
Clear memory: clears the entire memory
of the instrument.
Quit: exits the program.
Exported files have the following format (the words shown here between the delimiters <> are simply
placeholders for actual data. Entries are separated by tab characters. Depending on the settings,
some columns may be omitted):
# <Date> <Time>, <Inputs/Measurement modes>, <Sampling rate>, <Number of
measurement records>

9.4 Reading and saving measurement data
Reading and saving measured data with the
3B NETlog™ equipment:
The current version of the firmware will now be
installed automatically. As an alternative, use
"Browse" in the options' box to search and
install older firmware versions.

Connect the 3B NETlog™ equipment to a
computer via USB cable.
Start 3BNETdata and click on the tab
"Read Data".
Press Read and wait till the progress bar
reaches 100%.
Select the measurements you wish to be
saved from the list on the left.
Select columns that are to be written next
to the data.
Click Save selected data to files
Enter a file name for each measurement,
or accept the default name.
For further processing of the saved data,
use spreadsheet or data analysis pro-
grams.
10. Update Firmware
In the 3B NETdata software, click "Update
firmware" tab.
Follow the instructions in the left-hand
section of the software window and click
"Start" in the options box.
