	3. OPERATION
RPT	If the RPM4 has two Q-PRTs, allows pressure measurement from the two
	RPTs to be displayed simultaneously (see Section 3.3.6.4). This function is
	particularly useful in dual Q-RPT RPM4s with independent TEST ports to
	monitor two separate pressures simultaneously. It is also used to when the
	Hi Q-RPT is in differential measurement mode, to observe the line pressure
	measured by the Lo Q-RPT.
HI/LO	Records and displays maximum and minimum pressures measured (see
	Section 3.3.6.5). This function is used to keep track of the minimum and
	maximum pressure observed in a system over a period of time or to monitor
	if a pressure min/max limit has been exceeded..
FREEZE	Captures and displays the pressure measured by the active range of RPM4
	when the [ENT] key is pressed (see Section 3.3.6.6). This function is useful
	to record the pressure present at the time of an operator observed trigger
	event, for example when the needle of an analog gauge was on the nominal
	point or when a switch activates.
CLEAN	Blanks out the second line of the display (see Section 3.3.6.7). This function
	is used when a simple display of pressure measured by the RPM4 active
	range without additional information is desired.

OPERATION

To set the DISPLAY function press [DISPLAY] from the main run screen.

The display is:

The cursor is on the active DISPLAY function. main run screen with the selected function active.

Display menu choices include:

1avg 2rate 3dev 4RPT 5HiLo 6freeze 7clean

Selecting a display function returns to the

<1avg>	Display average pressure and standard deviation. Specify averaging time period
	(see Section 3.3.6.1).
<2rate>	Display pressure rate of change (see Section 3.3.6.2).
<3dev>	Display deviation of the measured pressure from a target value and specify
	the target value (see Section 3.3.6.3).
<4RPT>	Display the pressure measured by the second Q-RPT in RPM4s with two
	Q-RPTs (see Section 3.3.6.4).
<5HiLo>	Display the maximum and minimum pressure observed since HiLo reset
	(see Section 3.3.6.5).

<6freeze> Capture and display the value measured when [ENT] is pressed (see Section 3.3.6.6).

<7clean> Leave the second line of the display blank (see Section 3.3.6.7).

The DISPLAY selection is NOT range specific. A DISPLAY selection made in one range applies to all ranges.

The default DISPLAY function is Rate which causes the second line of the display to show “R” followed by the current rate of change of pressure in current pressure units per second. The default DISPLAY function in differential mode is RPT.
