Enter ‘1.6000’ followed by
ENTER
on the keypad. The highlighted field will be replaced by
‘1.6000’. Press
CLR
to return to the point-selection screen (Figure 6.3). You should see ‘1.6000’ on
this screen, as the Ps1&2 vacuum point. This indicates to the 6600-NG that the absolute pressure
on the Ps1 and Ps2 outputs is currently exactly 1.6000 inHg.
7.
Generate exactly QcinHg=0.000 and PsinHg=8.0000. Wait for a minimum of 5 minutes to allow
temperature effects to stabilize.
8.
Note (on the calibration report, not on the Remote unit) the 6600-NG’s Pt Actual value as the “As
Found” values for the Pt vacuum point. (See Figure 6.10)
9.
Press ‘
1
’ on the Remote to enter the Pt vacuum point. The screen will appear as follows.

10.
Enter ‘0.0000’ (or simply 0) followed by
ENTER
on the keypad. The highlighted field will be
replaced by ‘0.0000’. Press
CLR
to return to the point-selection screen (Figure 6.3). You should
see ‘0.0000’ on this screen, as the Pt vacuum point. This indicates to the 6600-NG that the
differential pressure on the Pt output is currently exactly 0.0000 inHg.
11.
Generate exactly QcinHg=30.0000 and PsinHg=8.0000. Wait for a minimum of 5 minutes to allow
temperature effects to stabilize.
12.
Note (on the calibration report, not on the Remote unit) the 6600-NG’s Pt Actual value as the “As
Found” values for the Pt full-scale point. (See Figure 6.10)
13.
Press ‘
2
’ on the Remote to enter the Pt full-scale point. The screen will appear as follows.
