Description
MID1 NEG
56
701, 702,
703, 704
Represents the field calibration differential pressure, as read from
DP1 RAW (Point 68), when the Remote Pressure Transmitter
calibrator is set to the MIDdle differential pressure (-0.050 in. of
water, -12.45 Pascals) for negative pressurization.
MIN1 NEG
57
701, 702,
703, 704
Represents the field calibration differential pressure, as read from
DP1 RAW (Point 68), when the Remote Pressure Transmitter
calibrator is set to the MINimum differential pressure (-0.005 in.
of water, -1.24 Pascals) for negative pressurization.
SIG1 PHASE
67
701, 702,
703, 704
When calibrating the sensor, the direction of flow through the
sensor needs to be verified. If DIFF PRES1 (Point 30) is reading
a negative value when it should read positive, and this point is
set to LO, toggle the point from LO to HI.
DP1 RAW
68
701, 702,
703, 704
Indicates RAW counts used for diagnostic purposes.
MAX2 POS
71
702, 704
Represents the field calibration differential pressure, as read from
DP2 RAW (Point 88), when the Remote Pressure Transmitter
calibrator is set to the MAXimum differential pressure (+0.170 in.
of water, 42.34 Pascals) for positive pressurization.
MID2 POS
72
702, 704
Represents the field calibration differential pressure, as read from
DP2 RAW (Point 88), when the Remote Pressure Transmitter
calibrator is set to the MIDdle differential pressure (+0.050 in. of
water, 12.45 Pascals) for positive pressurization.
MIN2 POS
73
702, 704
Represents the field calibration differential pressure, as read from
DP2 RAW (Point 88), when the Remote Pressure Transmitter
calibrator is set to the MINimum differential pressure (+0.005 in.
of water, 1.24 Pascals) for positive pressurization.
ZERO 2
74
702, 704
Represents the field calibration differential pressure, as read from
DP2 RAW (Point 88), when tape is applied over the Remote
Pressure Transmitter through-the-wall ports producing a zero
differential pressure (+0.000 in. of water, 0.000 Pascals).
MAX2 NEG
75
702, 704
Represents the field calibration differential pressure pulse
frequency, as read from DP2 RAW (Point 88), when the Remote
Pressure Transmitter calibrator is set to the MAXimum differential
pressure (-0.170 in. of water, -42.34 Pascals) for negative
pressurization. This value can be input directly by the operator or
can be input from the system.
MID2 NEG
76
702, 704
Represents the field calibration differential pressure, as read from
DP2 RAW (Point 88), when the Remote Pressure Transmitter
calibrator is set to the MIDdle differential pressure (-0.050 in. of
water, -12.45 Pascals) for negative pressurization.
MIN2 NEG
77
702, 704
Represents the field calibration differential pressure, as read from
DP2 RAW (Point 88), when the Remote Pressure Transmitter
calibrator is set to the MINimum differential pressure (-0.005 in.
of water, -1.24 Pascals) for negative pressurization.
SIG2 PHASE
87
702, 704
When calibrating the sensor, the direction of flow through the
sensor needs to be verified. If DIFF PRES2 (Point 31) is reading
a negative value when it should read positive, and this point is
set to LO, toggle the point from LO to HI.
