tira47e1 (2005-08) BPG402SPv1.cp 31
The gauge supports the following pressure units:
Coding (dec) Pressure unit
1001 COUNTS
1301 Torr
1302 mTorr (Micron)
1308 mbar
1309 Pascal
For safety reasons, it is not possible to change the pressure unit while
the gauge is cyclically interchanging data with a DP/V0 master.
The data unit setting can only be modified when the gauge is in the IDLE
status.
In cyclic data traffic, the data unit must be set in the User Parameter
Data. All settings previously made in acyclic data traffic are overwritten
(→ section "User Parameter Data").
If the data unit is set in one instance, that data unit setting applies to all
instances. Likewise, the data unit setting made in the User Parameter
Data is valid for all instances.
This parameter is set to "1".
