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