Fluke RPM4 manual Rate, Psi a Hi, 0001/sec, Current rate of change of pressure in current

3. OPERATION

Pressing [ENT] while in the Average DISPLAY aborts the current averaging period and causes a new one to begin. [ENT] can thus be use to trigger a new averaging period on demand.

In the Average DISPLAY the Ready/Not Ready indication applies to the result of the previous averaging period (see Section 3.2.1). <Ready> indicates that all readings during the previous averaging period met the stability criterion. <Not Ready> indicates that one or more readings were outside of the stability criterion.

Changing the pressure unit of measure, measurement mode or range while the averaging screen is active, starts a new averaging period.

To go to a DISPLAY other than Average, press [DISPLAY] and make a new DISPLAY choice (see Section 3.3.6).

3.3.6.2Rate

PURPOSE

To activate the Rate DISPLAY.

See Section 3.3.6 [DISPLAY],  Principle.

The AutoTest function (see Section 3.3.10) to AutoRange RPM4 based on DUT characteristics and run an automated test sequence is accessed by pressing [ENT] from the Rate run screen.

OPERATION

To activate the Rate DISPLAY press [DISPLAY], <2Rate>. Pressing <2Rate> returns to the main run screen with the Rate DISPLAY active.

With the Rate DISPLAY active the main run screen is:

	99.1135 psi a Hi
1. Current rate of change of pressure in current	R 0.0001/sec
pressure units per second.

The Rate DISPLAY is different and separate from the stability setting which is used to set the stability criterion on which the Ready/Not Ready indication is based (see Sections 3.4.3 and 3.2.1). The Rate DISPLAY only causes the current rate of change to be displayed and has NO affect on the stability setting or the Ready/Not Ready condition.
