2.2.5 Select Calibration Gas

This configurable option is available to allow the user to
select a different flammable gas from that which was
originally used to calibrate the instrument.
This action allows the instrument software to compensate
and thus display more accurate readings when detecting
the re-selected gas type.
When this option is displayed, as shown in Fig. 2.6, the
gas that was originally used to calibrate the instrument
is identified between two arrowheads.
Note: The instrument calibration certificate also
identifies the original calibration gas type.
To select a different gas type, press the yellow Left Hand
(LH) button
from Methane, Butane, Propane, Pentane and Ethanol.
When the required option is highlighted, press and hold
the green (RH) button
Note: Accuracy for the re-selected gas type is + 20%.
