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
offset
.
Cal date:20021117 IH
AbsPoffset: 187.4 Pa
If in
edit
mode, the calibration information fields can be edited. Edits to P
offset
are common
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.
PA: 0.0 Pa IH
PM: 1.000000
If in
edit
mode, the calibration fields can be edited. Pressing
[ENT]
in the PM field goes to

The value of PA is always in Pascal (Pa). The value of PM is dimensionless.
PPCH-G may also use external Q-RPTs mounted in RPM4 Reference Pressure Monitors.
Viewing and adjustment of RPM4 calibration information is performed locally on the RPM4, not
through PPCH-G (see the RPM4 Operation and Maintenance Manual).
