b) Display Measurement with Bluetooth
®
The app “BTLogger” permits simple display of the measured tem-
perature on a mobile end device, long-term measurement includ-
ing various monitoring functions and data recording of the meas-
ured values. In order to connect the thermo logger to a mobile end
device, proceed as follows:
• Switch on your mobile end device (tablet or smartphone) and
activate the function “Bluetooth
®
” on that device (see “Settings”
in your mobile end device).
• Tap the app “BTLogger” on your mobile end device to activate it.
• Switch on the thermo logger.
• In the display of the mobile end device, select “Couple new
device”.
• Now push the button “Bluetooth
®
” on your thermo logger for
about five seconds, as demanded by the app (see text in the
display) (figure 1, item 2). Once the Bluetooth
®
connection has
been established, this will be displayed by a brief double sound
signal at the thermo logger as well as the display of the con-
nected device in the app (device type and temperature display).
If you now select the newly coupled device on the display, the
app will switch to a new screen (also see figure 5). Regarding
this, observe the following notes in this chapter.
If the connection by Bluetooth
®
is not established, this
may be due to devices that are located in direct prox-
imity of your devices and also broadcasting using Blue-
tooth
®
or other devices (such as a router) may act as an
interfering signal. In this case, go elsewhere and start
coupling of the two devices again. It may also be helpful
to remove the battery from the thermo logger for approx.
30 seconds here (reset) or to push the “Reset button” on
the top of the housing (figure 1, item 3).
