•

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>

Index (tab) Absolute date/time (tab) Relative time (tab) <Quantity at ana-

logue input A>[<Unit for analogue input A>] (tab) <Quantity at analogue in-

put B>[<Unit for analogue input B>] (tab) Dig A (tab) Dig B (tab) Dig C

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.

11. Format of exported files

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.
