 OPERATION
To access the resolution function, press [SETUP],
<2res>. The display is: Display resltn: Hi
0.0010 %FS < and >
Use the cursor control keys to set the desired level of resolution. Press [ENT] to return to the
MAIN RUN screen with the new resolution setting active or [ESC] to make no changes.
The resolution setting is range specific. A resolution setting made in one range does NOT
affect other ranges.
The maximum resolution setting is limited in AutoRange ranges that are less than 10% of
the Q-RPT default full scale.
3.4.3 <3STAB>
 PURPOSE
To view and/or adjust the stability test that is the Ready/Not Ready criterion for the active Q-
RPT and range.
See Section 3.2.1 Pressure Ready/Not Ready.
 PRINCIPLE
RPM4 continuously monitors the rate of change of pressure measured by the active Q-RPT
and compares this rate to the active stability limit to make a Ready/Not Ready determination
(see Section 3.2.1). The stability function allows the stability limit to be adjusted by the user
to increase or decrease the stability required for a Ready condition to occur.
Default stability when using AutoRange is + 0.005% FS of active range span. Default
statbility when AutoRanging as part of an AutoTest is 10% of the DUT tolerance (see Section
3.3.4, Table 4).
The stability limit is separate and different from the Rate DISPLAY function (see Section
3.3.6.2) which allows the current rate of change of pressure to be displayed.
 OPERATION
To access the stability setting adjustment, press
[SETUP], <3stab>. The display is: Stability limit: Hi
0.5 psi/s
Edit the desired stability limit setting. [ENT] activates the stability limit for the active range
and returns to the main run screen Press [ESC] to return to the MAIN RUN screen with no
change to the stability limit.
The stability setting is range specific. A stability setting made in one range does NOT
affect other ranges.
