Chapter 1. Features and capabilities
1.1 Introduction
The dew.IQ is a single-channel hygrometer that measures
moisture content in gases. It is suitable for a wide range of
process conditions in applications that require real-time
moisture measurement.
The dew.IQ accepts any calibration range provided with
Panametrics probes (see Chapter 7, Specifications for more
information). It comes equipped with two high/low alarm
relays, one fault alarm relay, and a single analog output . It
also has on-board data logging capability using a micro SD
card.
1.2 Electronics
You can program the meter using the keys on the front panel
(see Figure 1 below). The dew.IQ universal power supply
accepts voltages from 100 to 240 VAC, or you may order the
24 VDC configuration.

1.3 Probes
The moisture probe is the part of the system that comes
in direct contact with the process. The dew.IQ uses any
Panametrics M Series probe (see Figure 2 below) or an
IQ.probe (see Figure 3 below) to measure dew point
temperature in °c or 0 F. The sensor assembly is secured to
the probe mount and is protected with a sintered stainless
steel shield (see Figure 2 below).
Note: Other types of shields are available upon request.

Chapter 2. Installation
2.1 Introduction
Installing the dew.IQ includes the following steps :
• Selecting the analog recorder output (see page 4)
• Mounting the electronics (see page 8)
• Mounting the sample system (see page 15)
• Installing the probe (page 16)
• Wiring the system (see page 18)
WARNING!
To ensure safe operation, the dew.IQ must be
installed and operated as described in this
manual. Also, be sure to follow all applicable
local safety codes and regulations for
installing electrical equipment.

2.2 Selecting the analog recorder output
Note: By default, the analog recorder output is set to the
current output.
Note: Customers must provide their own cable for
connecting the analog recorder output. Cables ranging
from 16 to 26 AWG are acceptable.
The dew.IQ has one isolated analog recorder output. The
analog recorder output provides either a current or voltage
signal, as determined by the position of switch S1 on the
main PC board.
Complete the following steps to check or reset switch S1 (see
Figure 8 on page 7):
WARNING!
Never connect line voltage or any other
power input to the analog recorder output
terminals.
1. Make sure the dew.IQ is turned OFF and unplugged.
For wall mount and bench mount units, remove the
dew.IQ from its enclosure before proceeding (see the
appropriate figures in Appendix A).
WARNING!
The dew.IQ must be isolated or disconnected
from all voltage sources before changing the
recorder output.

2.2 Selecting the analog recorder output (cont.)
2. Remove the screw at the top of the back panel (see Figure 4 below).
Figure 4: Back Panel (AC cord version shown)
3. Lift the back edge of the top cover (see Figure 5 below).
Figure 5: Lifting the Back Edge of the Cover

2.2 Selecting the analog recorder output (cont.)
4. Slide the cover toward the back of the dew.IQ (see Figure 6 below).
Figure 6: Sliding the Cover to the Rear
5. Lift the cover away from the enclosure (see Figure 7 below).
Figure 7: Removing the Cover

2.2 Selecting the analog recorder output (cont.)
6. Locate switch S1 (see the highlighted area in Figure 8 below).
CAUTION!
Use proper ESD grounding prior to setting the switch.
7. Set switch S1 to the desired position: V for voltage or Ifor current.
Figure 8: Switch S1 on the Main PC Board
8. After setting the switch, reinstall the cover and secure it with the rear enclosure screw. For wall mount and bench mount
units, reinstall the dew.IQ in its enclosure (see the appropriate figures in Appendix A).

2.3 Mounting the electronics
The dew.IQ is available in the following configurations:
• “Panel Mount” on page 8
• “Rack Mount” on page 12
• “Bench Mount” on page 13
• “Wall Mount” on page 14
Proceed to the appropriate section for mounting your dew.
IQ electronics.
2.3.1 Panel mount
The panel mount unit can be installed in a panel up to 0.25
in. (6 mm) thick. See Figure 43 on page 100, for the required
panel cutout dimensions.
IMPORTANT:
For Type 4X and IP66 installation, the dew.IQ must be
mounted in a rig id , flat panel using the panel gasket and
both mounting brackets provided.

2.3.1 Panel Mount (cont.)
To mount the dew.IQ in a panel with a 3.69”(94 mm) x 1.81” (46 mm) opening, refer to the figures and complete the following
steps :
1. Remove the side panel mount label prior to installation.
Figure 9: Removing Side Panel Mount Label
2. Slide the gasket along the dew.IQ and place it around the back of the display (see Figure 10 below).

5. Hold the chassis and lock each mounting bracket in place by sliding it toward the rear of the dew.IQ (see Figure 13 below).
Figure 13: Locking the Mounting Brackets in Place
6. Use a screwdriver to extend the bracket screws to the back of the panel and secure the dew.IQ in the panel cutout (see
Figure 14 below).

7. Using a feeler gauge behind the display, check the gasket compression , and tighten the bracket screws until the gap is
0.028” (0.71 mm)± 0.002” (0.05 mm), as shown in see Figure 15 below.

2.3.2 Rack mount
The rack mount dew.IQ is a half-rack sized component designed for mounting in a standard instrument rack. See Figure 42 on
page 99, for the dimensions.

2.3.3 Bench mount
The bench mount dew.IQ can be placed on any clean, flat , horizontal surface that provides adequate clearance around the
unit for proper operation and configuration. See Figure 44 on page 101, for the dimensions.
