Differential Pressure Monitor Owner’s Manual
Descriptor Address Application 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.
