3. OPERATION
Page 35 © 2007 DH Instruments, a Fluke Company
With the Deviation DISPLAY active the main run screen is:
1. Deviation of current pressure from the target
value.
2. Target value.
8998.2 psi a zH3
D -1.8 T9000.0
Pressing [ENT] from the main run screen when the Deviation DISPLAY is active
goes directly to the Target editing screen. This allows the target value to be changed
and without going through the DISPLAY menu.
If the pressure measurement unit or mode is changed while the Deviation
DISPLAY is active the target value remains at the same numerical value. It is NOT
converted.
To go to a DISPLAY other than Deviation, press [DISPLAY] and make a new
DISPLAY choice (see Section 3.3.6).
3.3.6.4 RPT
PURPOSE
To activate the RPT DISPLAY.
See Section 3.3.6, Principle.
OPERATION
For the sake of clarity, when describing the RPT DISPLAY, the Q-RPT displayed on
the top line of the display when the RPT function is selected is referred to as the “active”
Q-RPT. The other Q-RPT to be displayed on the second (bottom) line of the RPM4 display
is referred to as the “inactive” Q-RPT. It is “inactive” in the sense that all RPM4 functions
and settings such as UNIT and RES still apply to the “active” Q-RPT. To make changes to
the “inactive” Q-RPT, for example to change its pressure measurement unit, it must be
made the active Q-RPT by a conventional range change (see Section 3.3.1).
To activate the RPT DISPLAY, press [DISPLAY], <4RPT>. Operation returns to
the MAIN RUN screen with the inactive Q-RPT displayed on the display’s bottom
line. The range of the inactive Q-RPT is always the default range, not an
AutoRanged range (see Section 3.2.3).
