Edit the hold limit value if desired and press
[ENT]
to view the stability limit. The
next display is:
1. Active Q-RPT designator.
2. View/edit field of stability limit value in active
pressure unit of measure. Shows active
stability limit.
3. Active control mode (
<D>
for standard
dynamic,
<d>
for hi volume dynamic,
<S>
for
static).
Stability limit: IH
0.010 MPa/s D
Edit the stability limit value if desired and press
[ENT]
to return to the main run
screen with the edited values active.
See Section 3.4.6, Table 8 for default control limits.
Monotonic Control Mode
When monotonic control mode is active, the
[SETUP]
,
<6control>
,
<1limits>
display is:
1. Active Q-RPT designator.
2. View/edit field of pressure target limit value in
active pressure unit of measure. Shows
active target limit.
3. Active control mode (
<M>
for monotonic).
Target limit: IH
1.000 MPa M
Edit the target limit value if desired and press
[ENT]
to view the monotonic ramp
rate limit. The next display is:
1. Active Q-RPT designator.
2. View/edit field of monotonic ramp rate limit in
active pressure unit of measure per second.
Shows active rate limit.
3. Active control mode (
<M>
for monotonic).
Rate limit: IH
0.050 MPa/s M
Edit the target ramp rate if desired and press
[ENT]
to return to the main run
screen with the edited values active.
See Section 3.4.6, Table 8 for default control limits.
Ramp Control Mode
When ramp control mode is active, the
[SETUP]
,
<6control>

<1limits>
display is:
1. Active Q-RPT designator.
2. View/edit field of pressure ramp rate hold limit
value in active pressure unit of measure per
second.
3. Active control mode (
<R>
for ramp).
Rate hold limit: X1H
0.100 MPa/s R
Edit the ramp rate hold limit value if desired and press
[ENT]
to return to the
main run screen with the edited values active.
