9.1 Preparatory steps
‣Connect the device.
 The device starts up and transmits the measured value as a current value.
To operate via the SmartBlue, the Bluetooth® LE signal on the smartphone or tablet must
be switched on.
9.2 Function check
LWARNING
Incorrect connection, incorrect supply voltage
Safety risks for staff and device malfunctions!
‣Check that all connections have been established correctly in accordance with the
wiring diagram.
‣Ensure that the supply voltage matches the voltage indicated on the nameplate.
Familiarize yourself with the operation of the device before it is first switched on. In
particular, please read the "Basic safety instructions" sections. After power-up, the device
performs a self-test and then goes to the measuring mode.
