at least three seconds, one of the buttons at
the lower part on the right of the keyboard

The phase of warming up and auto calibration
takes about 1 minutes after switching on the
instrument.
When finished, the device automatically
changes to the PPM scale.
ATTENTION:
Switching on of the instrument must take
place in place free from gas.
