The table below shows the displayed readings at various pressures for selected gases.
Pressures shown in bold italic font in the shaded areas are in x 10
Pressures shown in normal font and in non-shaded areas are in mbar. Note only the green LED is illuminated.
Pressures shown in normal bold font with an asterisk(*) in the shaded areas are in bar. Note only the red LED is illuminated.
