Measurement unit
Measurement unit of the measurement value, switching
threshold value, etc.
→ Appendix 88 for Conversion
table.
This parameter setting is also effective for
ITR 90 and ITR 200 gauges.
Value
Ö mbar/bar
Ö Torr
(only available if
Torr lock disabled
→ 54)
Ö
Pascal
Ö Micron
(=mTorr)
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.
Correction factor
Not for CTR 90, CTR 91, CTR 100, CTR 101,
DI 200, DI 201, DI 2000, DI 2001 and
DI 2001 rel linear gauges.
For ITR 90 and ITR 200 Ionization/Pirani
vacuum gauges only for pressures
<1×10
-2
mbar.
For Pirani/Capacitive gauges TTR 100,
TTR 100 S2, TTR 101 and TTR 101 S2 only for
pressures <10 mbar.
The correction factor allows to convert the measurement
value for other gases than N
