8.3 Touchscreen
You only need three touchscreen movements to use the testo 400:
Description
Tapping
To open applications, select menu icons, press
buttons on the display or enter characters with the
keypad, tap these with a finger in each case.
Swiping
Swipe to the right or left on the display to show
further views, e.g. to switch from the list view to the
graphic view.
Zooming
In order to make a section of the display larger or
smaller, touch the display with two fingers and
move them apart or together.
8.4 Setup wizard
When the testo 400 is started up for the first time, the setup wizard is activated
and guides you step-by-step through the following setting parameters.
The instrument setup that is implemented can be adapted at any time in
the Settings menu.
8.4.1 Select language
The first step is to select the language for using the testo 400.

8 Commissioning
19
8.4.2 Country settings and units
In this step, you have the option of selecting the country and of deciding whether
you want to use the metric or imperial unit system. It is also possible to establish
user-defined settings for the units. See Section 10.3.1 and 10.3.3.
8.4.3 WLAN
Click on the WLAN field to connect the testo 400 to the internet. Here,
connection to a known WLAN must be established. The icon at top right
allows you to manually add networks, call up saved networks and update
available networks. In addition, further adjustments can be made via Advanced.
For password-protected networks, you need to enter the password. On
secured networks, various ports may be blocked, restricting the creation
of e-mail accounts and the sending/receiving of e-mails.
The WLAN connection can be used for various functions:
•Automatic notification of information for updates
•Carrying out updates of the instrument firmware (see Section 10.1)
•Sending measurement reports as PDF files and measurement data as .json
and .csv files via e-mail (see Section 9.6)
•Using the internet browser via the Other applications menu (see Section
10.4.5)
If the WLAN reception is not sufficient, the error message Network
disabled appears. Try connecting the testo 400 to a better WLAN
network.
8.4.4 Date and time
Click on the Time field to set the date and time. It is possible to automatically
retrieve the date/time via network or GPS or to set it manually. The time zone
can also be set automatically/manually and you can choose between 12-
hour/24-hour mode.
We recommend that you select Use network-provided time as the setting.
Please also see Section 10.3.1.
8.4.5 Contact information/company details
On each line, personal details can be entered for the items Company /
Technician name / Street, building number / Postcode, city / Country /
Telephone / Fax / E-mail and Homepage. In principle, company details can also
be inserted using the testo DataControl software. The company details will be
displayed in all PDF reports at the top right of the document and also listed in
the measurement data report. The company details stored in the testo 400 at
the time of the measurement cannot be subsequently changed in the PDF report

of the measurement. The new company details will only be stored in the PDF
report once a new measurement is carried out. Please also see Section 10.3.4.
8.4.6 Setting up an e-mail account
Click on the E-mail field to connect an e-mail account to the testo 400
measuring instrument, so that you can send measurement data reports via e-
mail. See also Section 10.2.
8.5 Tutorial
At the end of the Setup wizard, the tutorial can be launched.
The tutorial can be executed again at any time via the Help and
Information menu.
The tutorial demonstrates the general operation and the most important
functions of the measuring instrument, using brief examples. The detailed
descriptions can be found in the relevant sections.
