INTRODUCTION
The HygroPort I.S. Advanced Dewpoint Hygrometer is a portable instrument designed
for the on-line measurement of moisture content in non-corrosive gases in hazardous
locations, over an operational range of -148 to +68°F (-100 to +20°C).
The instrument is independently assessed and certi
fi
cated as being intrinsically safe and
fully compatible with safe operation for Class I, Division 1, Groups A, B, C, D and Class
1, ZONE 0.
The instrument is contained within a rugged case, sealed to NEMA4 (IP66) standard
and is powered by an internally mounted Nickel Metal Hydride (NiMH) battery
designed to typically provide 24 hours continuous use between charges. Continuous
battery charge status indication is provided. Additional battery status information
is provided by a “battery low” warning beep and indicator. The HygroPort I.S. is
equipped
with an internally mounted ceramic sensor, which is enhanced for a quicker
response to dewpoints as dry as -103°F (-75°C) dewpoint.
A graphical display presents the dewpoint data in large format characters and
simultaneously provides a primary display of real time dewpoint readings and a
secondary display, in smaller characters, for the external transmitter input. If no
external input is programmed, gas temperature, measured by the internal sensor, is
displayed by default
.
A fully programmable, real-time, datalogging facility is provided which has an internal
memory capacity of 8Mb, capable of storing up to 10,000 logs per file (typically giving
a maximum of 64 log
fi
les).
A Bluetooth, wireless communication system is provided, giving access to a dedicated,
PC-based HygroPort I.S. Software Application Package which provides the facility
for handling the logged data files and uploading and downloading instrument
parameters
.
A user-friendly operator interface provides easy access to all levels of the instrument’s
functions.
An easy to follow calibration routine is built into the instrument’s software.
The
calibration routines are described in Section 7.
Two versions of the instrument are available, a HygroPort (standard) version and
this HygroPort I.S.
(intrinsically safe) version.
This manual covers the HygroPort I.S.
version only
.

Function Keys
The
function keys,
located
below
the
display, are used to select operations from
the Main Menu level (selected by the center
key), to enter sub-menu levels and to select
and enter parameter variables within those
menu levels.
The function key panel is shown (right)
and the operation of the keys is as follows:
Enter key. Operation of this key from the
front page display causes the Passcode
Display Screen for entry to the Set-up menus
to be displayed.
The Passcode PIN must then be entered,
using a combination of the
(up) and
(down)
keys located above and below.
After each digit is selected, this Enter key
should be pressed in order to accept the
entered digit. Within the Settings menu
and sub-menus, this key is used to highlight
and select options and to accept entered
values. The passcode pin is 7316.
Scroll down key. From the
Passcode entry page, this key is used to
reduce the value of the highlighted
passcode entry digit.
Within the Set-Up Menu this key is used
to highlight one of the Settings sub-menu
options for entry to that level which is then
entered by pressing the Enter key.
Within sub-menus this key is used to scroll
down and highlight options available for
selection within that sub-menu.
Within sub-menu levels requiring the entry
of alpha numeric values e.g. for the entry
of datalog parameters, this key is used to
decrease the currently displayed value i.e
.
(Z-A, 9-0). Pressing the key once decreases
the selected field by one step. Pressing and
holding the key will cause the selected
fi
eld
to be continuously decreased until the key
is released.

Within sub-menus this key is used to scroll up
and highlight options available for selection
within that sub-menu.
Within sub-menu levels requiring the entry
of alpha numeric values, e.g. for the entry
of datalog parameters, this key is used
to increase the currently displayed

Pressing and holding the key will cause the
selected field to be continuously increased
until the key is released.
Scroll right key. Within the Logging
(datalog) sub-menu levels, where the
entry of alpha numeric characters is
required, this key is used to shift the
insertion point right in the file name entry
field.
At each position, a combination of the
scroll up and scroll down keys is used to
select the required alpha numeric value.
When the full field name has been
entered, the fi ile is created by pressing
the Enter key.
Scroll left/Escape. Within any menu or sub-
menu level, pressing this key escapes to the
next highest menu above the current level. For
example, to return to the Main Display from
the Input Passcode screen press this key once.
Similarly, to return to the Settings menu from
any of its sub-level menus, press this key once.
Within the Logging (datalog) sub-menu levels,
where the entry of alpha numeric characters is
required, this key is used to shift the insertion
point to the left in the f i l e name entry

Instrument Display
The instrument display is divided into three distinct areas - a primary display area, a
secondary display area and a status display area (refer to Item 2 in Table 2.1).
During normal operation, the internal sensor is configured as the primary (large
character) display and can be configured for either internal temperature or external
transmitter reading, depending upon how the instrument has been set up.
The graphics display and the associated function keypad (
Figure 2.1),
form the operator
interface of the equipment.

Instrument Start-Up
When turned on, the instrument goes through an initialization process of between 4
and 7 minutes, depending on the sensor and sample gas characteristics, during which
time the internal sensor is heated to a maximum of 140°F (60ºC). The heating
process excites the moisture molecules already present in the sensor and accelerates
equilibration with the moisture content of the sample gas. During this period the
sample gas
fl
ow purges the
system
. After this period, the sensor will be dried to
below the dewpoint of the gas to be measured. The heating is then switched off and
the display flashes.
Figure 2.4
shows a typical start-up sequence.
When turned on, the System Initializing screen is displayed for a period of
approximately five seconds; following which the Initialization screen is displayed for a
period of 1 minute. Thereafter the screen will show a countdown time of the
remaining initialization time
.
During this period, gas will be
fl
owing through the sensor and can be externally regulated
to meet the instrument’s fl low requirements. The real time sensor temperature is
indicated in the secondary display area.
The Initializing icon (item 6 in
Figure 2.3)
is
displayed in the status area. The keyboard, with the exception of the scroll up and
scroll down
keys, is locked out, as indicated by the keyboard lock icon (item 4 in
Figure
2.3)
, until the initialization period has expired.
Note that it is possible to terminate the
initialization process before the initialization period has timed out by pressing the scroll
up and scroll down keys simultaneously. This action aborts the instrument’s response
enhancement system but allows the operator to make an immediate measurement if
the measured dewpoint is wetter than –4°F (-20ºC) dewpoint.
While the initialization process is in progress, the backlight time-out is precluded and,
if any external transmitter has been configured and connected to the instrument,
display of the external transmitter reading is also precluded. After the end of the
initialization period, the display reverts to the measurement mode displaying the
dewpoint (in the currently selected unit) in the primary display area, and any external
transmitter reading in the secondary display area. By default, the internal temperature
is displayed in the secondary display area if no external transmitter is
configured.
When the reading has been acquired, and the instrument has been dynamically
tracking it for a given period, a message, Measurement OK, indicates that the
instrument is stable and reading within 0.9°F (0.5°C) for two minutes.
