To view or edit Q-RPT calibration information press [SPECIAL], <8Cal>. Select the desired
Q-RPT. The <1view> selection displays the calibration information fields. The <2edit>
function displays the fields and allows them to be edited. The display is:
1.
Date of last calibration in YYYYMMDD format.
2.
Position designator of the Q-RPT being viewed.
3.
Current value of absolute mode P
If in edit mode, the calibration information fields can be edited. Edits to P
with changes made in the AutoZ edit or run function (see Section 3.5.1). Pressing [ENT] on
the last field goes to the next view/edit screen:
1.
Value of PA.
2.
Position designator of the Q-RPT being viewed.
3.
Value of PM.
If in edit mode, the calibration fields can be edited.
[ENT] in view mode returns to the view/edit screen. [ENT] in edit mode goes to confirmation of
change activation if changes have been made in any of the calibration screens. Pressing [ESC] in
any edit screen exits the edit screen without activating any changes.
The value of PA is always in Pascal (Pa). The value of PM is dimensionless but should be
very near 1.

Q-RPT CALIBRATION/ADJUSTMENT WITHOUT CALTOOL
FOR RPTS SOFTWARE
PRINCIPLE
The RPM4-AD Q-RPTs can be calibrated and adjustments made without using CalTool for
RPTs software. This requires:
•
Applying pressures with a calibration standard and recording the pressures measured by
RPM4-AD.
•
Calculating new PA and PM values and entering them.
•
Setting P
to zero.

Before proceeding to calibrate a reference pressure transducer without using CalTool for RPTs
software, Sections 5.2, Calibration of Reference Pressure Transducers, 5.2.1
5.2.2 Equipment Required, 5.2.3 Setup and Preparation should be reviewed thoroughly.
