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 Bluetooth
®
button on your thermo logger for about
five seconds, as demanded by the app (see text in the display)
(figure 1, item 1). Once the Bluetooth
®
connection has been es-
tablished, this will be displayed by a brief double sound signal
at the thermo logger as well as the display of the connected
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 rear of the housing (figure 1, item 3).
