RPM4/HPMS A70M/A20M-AF OPERATION AND MAINTENANCE MANUAL

Press [ENT] to save the range or [ESC] to return to the MAIN RUN scree n w i t ho u t

saving the range.

Default (<DF>) Q-RPT ranges cannot be saved. They are permanent.

Duplicate AutoRange ranges cannot be saved. A duplicate AutoRange range is

a range that has the same measurement mode and full scale and uses the same Q-

RPT as a range that has already been saved.

 OPERATION

To delete a single saved AutoRange range, press [SETUP], <1range>, <2delete>.

If there are any saved ranges available to delete, the display is:

1. Indication that the cursor control keys may be

used to toggle through the saved ranges to

select the one to be deleted.

2. Designator and position of the Q-RPT used by

the range to be deleted.

3. Pressure unit of measure of the range to be

deleted.

4. Full scale pressure of the range to be deleted

in gauge mode and absolute mode if available.

3.4.2 <2RES> (RESOLUTION)

 PURPOSE

To set the resolution with which measured pressures and other pressure indications and

settings are displayed.

 PRINCIPLE

The resolution with which RPM4 displays pressure values can be adjusted. This feature can be

used to reduce the resolution when lower precision measurements are being made and excess

resolution might confuse or distract the operator.

The resolution setting determines the number of digits with which pressure is displayed. The

resolution is calculated based on the span of the range and then rounded to the furthest digit to

the right. For example, resolution of 0.001 % on a range of 1 500 psi is 1 500 X 0.001 % = 0.015

which is rounded down to 0.01 psi.

Default resolution is 10 ppm of active range span. Resolution is set automatically by

AutoRange (see Section 3.3.4) and by AutoTest initialization (see Section 3.3.10).
