Special case of revision with orifice flow meter

If the coordinate ED01 Revision mode is switched from "Operation" to "Revision"
in menu E Mode, submenu ED Access, it is possible to follow the measurement
values of the pressure cells during the check of the individual delta-p cells in
GZ Orifice function key. The corresponding current inputs of the cells are dis-
played in menu AP diff.pressure.
Therefore, during the check of a delta-p cell, the entire range can be monitored
from 0 to max. value.
There are 2 revision modes:
"Revision"
"Revision via contact"
Coordinates ED13 total. in revision, ED14 Temp. at revision and ED15 Pres-
sure at revision define the behavior of the ERZ2000-NG during the revision:
If the totalizers stop during the revision, "At rest" must be selected in ED13. If
pressure or temperature should remain at the last valid temperature during a revi-
sion, "retained value" must be selected in ED14 and ED15.
