Notes:
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 mea-
surement of 10 Torr. True pressure of nitrogen is 10 Torr.
2) Gas used is argon (Ar). Display shows pressure measure-
ement 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.

Display - mbar
The table below shows the displayed readings at various
pressures for selected gases when engineering units selected is
in mbar.
Displayed pressure readings vs. true pressure for selected
gases - engineering units in mbar (see following table):
