6.1 Display - Torr / mTorr
The table below shows the displayed readings at various pressures for selected gases when engineering units
selected is in Torr/mTorr.
Displayed Pressure Readings vs. True Pressure for selected gases
Pressures shown in bold italic font in the shaded areas are in mTorr.
Pressures shown in normal font and in non-shaded areas are in Torr.

1) OP = overpressure indication: display will read over pressure
2) Display auto-ranges between Torr and mTorr at 1 Torr
Examples:
1) Gas used is nitrogen (N
2
). Display shows pressure measurement of 10 Torr. True pressure of nitrogen is 10 Torr.
2) Gas used is argon (Ar). Display shows pressure measurement of 600 mTorr. True pressure of argon is
1 Torr.
3) Gas used is oxygen (O
2
). Display shows pressure measurement of 486 mTorr. True pressure of oxygen is 500 mTorr.
