The dewpoint demand system consists of three components. First, a probe that reads system dewpoint
and transmits a 4-20 ma signal to the second component, a digital display that interprets and displays it
in °F pressure Dewpoint. The third component is the 24V DC power supply that supplies power to the
probe for loop power signal and the probe's auto calibration routine. All must be working in concert to get
an accurate dewpoint reading. Each dewpoint meter comes pre-programmed with manufacturers'
settings, and should not require any field adjustments. Cases, in which adjustments must be made, refer
to parameters instructions and the factory standard values chart below.
Press PAR to enter into PRO display, using the
F1▲/F2▼scroll to the program group that may need
adjustments. Once found, press PAR to select the
specific parameter that needs adjusting, followed by
F1▲/F2▼to change settings. Pressing PAR will finalize
any action. Pressing DSP at any time will return the
meter to the current dewpoint reading.

Bullet Points
1.
Verify there is flow over
the sample cell. It should be
fed by an unrestricted
compressed air line. The flow
restriction is created by a
check valve and orifice on the
outlet of the sample cell, just
before the "pigtail" that
prevents ambient moisture
from backtracking to the
sensor.
2.
Verify that the data
cable is securely connected to
the probe.
3.
Verify the 24V DC
power supply is supplying the
correct voltage.
