Unit of measured values, thresholds etc. See Appendix
(
→  81) for conversion.
Value
Ö mbar/bar
Ö Torr (only available if
Torr lock is not activated
i.e. Torr is not sup-
pressed
→  50)
Ö Pascal
Ö Micron
(=mTorr)
A change of the pressure unit influences also the settings
of the BPG, HPG and BCG gauges.
When selecting Micron, above 99000 Micron the readout
automatically changes over to Torr. When the pressure
drops below 90 Torr the instrument automatically
switches back to Micron.
The correction factor allows the measured value to be
calibrated for other gases than N

"Literature"  86).
