Quickstart guide
Gasman warm up sequence
a) The unit will test the alarm
LEDs, sounder, vibration alerts,
and the operator display
screen. The sounder may
be silenced by pressing the
button.
b) The unit will continue through a warm up sequence as shown
below, this will take approximately 20 seconds.
c) Autozero
If Autozero is enabled (default), the unit will display the Autozero
confirm screen: the display will alternate between 'ZERO' and
'????'. Press the operator button with a single click to confirm
Zero. If the operator button is not pressed within the 10 second
time out, Gasman will proceed directly to Run mode without
performing Zero.

Your unit is now ready to use.
Familiarise yourself with the gas being
monitored in your unit and make sure you understand site health
and safety procedures in the event of alarm conditions.
