OPERATION
To set custom control parameters, press the [CUSTOM CONTROL] key from the main
run screen. The display is:
1. Current reference transducer ( <H> for high) and
range ( <1> , <2> or <3> ).
2. Current control mode setting for this range ( <S> for
static, <D> for dynamic).
3. Entry field for setting the desired hold limit. Recalls
the default hold limit or the last custom hold limit set
for the currently active range.
Enter the desired hold limit. The next display is:
1. Current reference transducer ( <H> for high, <L>
for Lo) and range ( <1> , <2> or <3> ).
2. Current control mode ( <S> for static, <D>
for dynamic).
3. Entry field for setting the desired stability limit.
Recalls the default stability limit or the last custom
stability limit for the currently active range.
Enter the desired stability limit. The display returns to the main run screen with the
custom control parameters active.
To reset default control parameters for a range and control mode, select the control
mode using the CONTROL function while in that range.
Custom control parameters are range and control mode specific. Changes made in one
range and control mode are stored for that range and control mode and will be recalled
when that range and control mode is returned to. Changes made in one range and
control mode do not affect any other range control mode setting.
When custom control parameters are active, a <C> is appended to the control mode
indicating character (<S> for static, <D> for dynamic) in the middle of the bottom line of
the main run screen (see Section 3.1.1).
3.2.6.1 TURNING-OFF CUSTOM CONTROL PARAMETERS
To return to default pressure control parameters for the active range and
control
mode, select the control mode using the CONTROL function
(see Section 3.2.3). Making a control mode selection automatically sets the control
parameters to default values.
