3. OPERATION

3.3.6.4RPT

PURPOSE

To activate the RPT DISPLAY.

See Section 3.3.6,  Principle.

The RPT DISPLAY is only available in RPM4s with two Q-RPTs.

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 measurement units, it must be made the active Q-RPT by a conventional range change (see Section 3.3.1). In differential pressure measurement mode, the Hi Q-RPT is always the “active” Q-RPT.

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 3.3.4).

If the RPM4 has only one Q-RPT, <Not available with single RPT> displays momentarily and operation returns to the main run screen when [DISPLAY], <4RPT> is pressed.

If the RPM4 is in parallel (<HL>) (see Section 3.5.7.3) mode in which both Q-RPTs are used simultaneously, when <4RPT> is selected, the Q-RPT to display on the lower display line must be specified. The Q-RPT specific settings of the Q-RPT displayed in the lower display line (measurement mode, unit of measure, resolution, etc.) can only be changed by making that Q-RPT active.

With the RPT DISPLAY active the main run screen is:

1.Active RPT display.

2.Inactive RPT display with Ready/Not Ready indicator on far left.
