Turning Off Absolute and Negative Gauge
Measurement Modes for Axxx (Absolute) Q-RPTs
PURPOSE
To prevent operation in absolute and negative gauge measurement modes with an Axxx
(absolute) Q-RPT.
PRINCIPLE
Axxx (absolute) Q-RPTs are frequently used in gauge measurement mode only (see Section
3.2.11). Axxx Q-RPTs that are used in gauge mode only, may be calibrated in gauge mode
with a reference that applies gauge pressures. Calibration with an absolute reference is not
necessary. However, if an Axxx Q-RPT is calibrated in gauge mode, it is not possible to know
if it is in or out of tolerance in absolute and negative gauge modes. To avoid using absolute
and negative gauge measurement modes on an Axxx Q-RPT that is calibrated for gauge mode
only, access to absolute and negative gauge modes can be turned ON and OFF.
OPERATION
Note
See Section 7.2.7 for more detailed information on editing and viewing
Q-RPT calibration information.
Caution
As editing PA and PM values will change the calibration of the Q-RPTs, the
edit function should only be used by qualified personnel as part of the
calibration process. Caution should be taken to avoid accidental editing.
A user level security system is available to control access (see Section
3.2.26.5).
7.2.5.1 Basic Interface
Turning absolute and negative gauge mode operation ON and OFF for a Q-RPT
occurs in the same area in which calibration coefficients is edited. To access the
Q-RPT calibration editing area use
<Spec>, <Cal>
and select the desired Q-RPT.
Then
<Edit>
to make changes.
through the calibration information.
After viewing the values of PA and PM the
display is:
Absolute and
neg g mode:
♦Off ♦On
The cursor is on the number corresponding to the current selection. Make the
desired selection.
<On>
causes absolute and negative gauge modes to be
unavailable for the Q-RPT.
7.2.5.2 Advanced Interface
The Gauge Only setting is located in the
[Settings], <More >>>, <Calibration>,
<Hi RPT> or <Lo RPT>, <Calibration>
screen.
If security is
