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-

<2RES> (RESOLUTION)
PURPOSE
To set the resolution with which measured pressures and other pressure indications and
settings are displayed.
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.
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.

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).
