MEASUREMENT
SPAN
When it is necessary to change the configuration of the equipment,
you should use SigNow software, TxConfig software, or SigNow
100 °C / 212 °F
app.
100 °C / 212 °F
To configure the equipment through any of the software, you must
400 °C / 752 °F
connect the TxConfig Configuration Interface (purchased from the
manufacturer or its authorized representatives) to the USB port of
400 °C / 752 °F
the computer used and run the selected software, as shown in
100 °C / 212 °F

To configure the device via SigNow app, you need to use an OTG
cable with the TxConfig Configuration Interface and proceed with
the recognition process (see
chapter).
On NOVUS website, you can download the configuration software
for free. To install it, simply run the file SigNowSetup.exe or the file
TxConfigSetup.exe and follow the instructions in the installer.
The SigNow setup application can be downloaded for free from the
Google Play Store or the App Store.
