Enter ‘30.0000’ (or simply 30) followed by
ENTER
on the keypad. The highlighted field will be
replaced by ‘30.0000’. Press
CLR
to return to the point-selection screen (Figure 6.3). You should
see ‘30.0000’ on this screen, as the Pt full-scale point. This indicates to the 6600-NG that the
differential pressure on the Pt output is currently exactly 30.0000 inHg.
15.
Generate exactly QcinHg=0.0000 and PsinHg=38.0000. Wait for a minimum of 5 minutes to allow
temperature effects to stabilize.
16.
Note (on the calibration report, not on the Remote unit) the 6600-NG’s Ps1 and Ps2 Actual values
as the “As Found” values for the Ps1 and Ps2 full-scale point. (See Figure 6.10)
17.
Press ‘
4
’ on the Remote to enter the Ps1&2 full-scale point. The screen will appear as follows.

18.
Enter ‘38.0000’ (or simply 38) followed by
ENTER
on the keypad. The highlighted field will be
replaced by ‘38.0000’. Press
CLR
to return to the point-selection screen (Figure 6.3). You should
see ‘38.0000’ on this screen, as the Ps1&2 full-scale point. This indicates to the 6600-NG that the
absolute pressure on the Ps1 and Ps2 outputs is currently exactly 38.0000 inHg.
19.
The calibration points have now been entered. You should be in the screen shown in Figure 6.3.
Press
GO
to save the points and exit this screen. If you press
CANC
, the calibration will be void.
When GO is pressed, the screen will appear similar to the one shown below.
