Offsets are entered through Hyperterminal as follows:
For Ps1 offsets: Sn=xxxx followed by ENTER
For Ps1 offsets: Dn=xxxx followed by ENTER
For Pt offsets: Pn=xxxx followed by ENTER
where n is the offset number between 1 and 9, and ‘xxxx’ is the positive or negative offset value equal to
(Actual value – Pressure Standard value).
For example, at point 2 (Pressure Standard = 3.8000 PsinHg), if the 6600-NG Ps1 Actual value is 3.7982,
the offset value will be (3.7982 – 3.8000 = -0.0018), and the command sent to the 6600-NG would be:
S1=-0.0018 followed by ENTER
At point 2, if the 6600-NG Ps1 Actual value is 3.8015, the offset value will be (3.8015 – 3.8000 = 0.0015),
and the command sent to the 6600-NG would be:
S1=0.0015 followed by ENTER
If the commands are sent correctly, the 6600-NG will echo back ‘0’. When the offset is entered, the 6600-
NG Actual value (Pt, Ps2 or Ps1) will immediately change to reflect the correction made due to the offset
