3.5.4 Switching the device on and off
• Connect the device to the electric
mains via the AC adapter and switch
it on by pressing the On/Off switch
at the back. The system starts up
with a single beep and runs a self-
check.
ǽ The device does not require a cali-
bration before performing measure-
ments. The analyzer software checks
the system each time the analyzer is
turned on. During testing, the ana-
lyzer automatically checks and cor-
rects its performance based on the
independent internal sensor.
• Switch off the device by tapping the button on the Main or the Login screen.
