correction. View and toggle through active Q-
RPT and setup shortcuts.
[ENT]
on a Q-RPT or shortcut activates it.
SDS controls the connection of the
Q-RPT to the
TEST(Pt) and/or
TEST(Ps) port. Closes any open
SDS. Opens SDS of active Q-
RPT if closed.
Select pressure unit of measure for
the active range. Choice of units
available in this menu depends on
current measurement mode.
Choice of units can be customized.
Run the AutoZ function to
AutoZero the active Q-RPT and
measurement mode.
Select the pressure measurement
mode for the active Q-RPT
(absolute, gauge, negative gauge,
differential).
This function is not used in RPM4-
AD models. Menu of less commonly used internal
functions and settings.
Run automated leak checking
routine, also used for average rate

3.3 DIRECT FUNCTION KEYS
3.3.1 [RANGE]
 PURPOSE
To view and/or change the active Q-RPT and associated settings. Includes direct shortcuts
to air data measurement modes.
 PRINCIPLE
RPM4-AD has two Q-RPTs.
In RPM4 A160K/A160K, the two Q-RPTs may be used in parallel ( <HL> ) or the Hi Q-RPT
may be used alone ( <Hi> ) or in true differential mode with the Lo Q-RPT ( <Hd> ).
In RPM4 A350K/A160K, the Hi Q-RPT ( <Hi> ) or the Lo Q-RPT ( <Lo> ) may be used
individually. Differential use of the two Q-RPTs is accessed by selecting the Hi Q-RPT
(
<Hd> ). Parallel mode of the two Q-RPTs is not supported.
The [RANGE] function key is used to specify which Q-RPT (and associated range and settings) is
active.
To streamline RPM4-AD operation, the [RANGE] key also provides simple shortcuts to the
RPM4-AD configurations that support air data measurements.
See Section 4.4.5 for procedures to accomplish the same air data setups as [RANGE]
shortcuts using remote commands.
