routine and automatically switch OFF the instrument.
Alternatively, a configurable option is available to force the user
to switch OFF the instrument.

2.2.7 Select Calibration Gas
This configurable option is available to allow the user to
measure a different flammable gas from that which was
originally used to calibrate the instrument.
This action allows the instrument software to compensate and
display more accurate readings.

When this option is displayed, as shown in Fig. 2.8, the gas
that was originally used to calibrate the instrument is identified
between two arrowheads.

to step through the available options from Methane,
Propane, Butane and Pentane.
