1. GENERAL FEATURES
HD32.2 is designed for WBGT (Wet Bulb Globe thermometer temperature) index analysis in pres-
ence or absence of solar radiation. The instrument is provided with three inputs for probes with SI-
CRAM module: the probes have an electric circuit that communicates with the instrument; the sen-
sor calibration data are saved in its permanent memory.
All the SICRAM probes can be inserted in one of the inputs: they are automatically recognized
when you switch the instrument on.
The main features of the instrument are:
•Logging: acquisition and memorization of data inside the instrument. Memory capacity: 64
different logging sections, with the possibility to set the acquisition interval of the samples.
You can set the duration of the memorization and, with auto-start function; it’s possible
to set the starting and finishing date and the hour of data memorization.
•The measurement unit of the temperature visualized sizes: °C, °F, °K.
•The system date and hour.
•The visualization of the maximum, minimum and medium statistic parameters and their
cancellation.
•The transfer speed of the data through the serial port RS232.
NOTE: The set acquisition interval is the same for all the probes connected to the instrument.
HD32.2 instrument can contemporarily detect the following sizes:
•Globe thermometer temperature Tg.
•Wet bulb with natural ventilation temperature Tn.
•Ambient temperature T.
On the basis of the detected measurements, HD32.2 can calculate:
•WBGT(in) index (Wet Bulb Glob Temperature: wet bulb and globe thermometer tempera-
ture) in presence or absence of solar irradiation.
•WBGT(out) index (Wet Bulb Glob Temperature: wet bulb and globe thermometer tempera-
ture) in presence of solar irradiation.

2. WORKING PRINCIPLE
Microclimate term means the environmental parameters that influence the thermal exchanges be-
tween the being and the environments inside limited places and that determinate the so-called
“thermal well-being”.
The micro-environmental weather factors together with your own job influence a series of your bio-
logic responses connected to well-being situations (Comfort) or thermal uneasiness (Discomfort).
In fact, the human body tries to keep the thermal balance in equilibrium conditions in order to keep
the body temperature on optimal values.
HD32.2 detects the following sizes:
•tnw: wet bulb with natural ventilation temperature probe
•tg: globe thermometer temperature
•ta: ambient temperature
It realizes direct measurements with the probes connected to the instrument and it also calculates
and directly visualizes WBGT index.
WBGT (Wet Bulb Globe Temperature) - wet bulb and globe thermometer temperature - is one of
the indexes used for determining the thermal stress to which is submitted a being in a warm envi-
ronment. It represents the value, with reference to the metabolic waste connected to a special job,
over which the being is in a thermal stress condition. WBGT index combines the temperature meas-
urement of natural ventilation wet bulb tnw with the Glob thermometer tgand, in some situations,
with the air temperature ta. The formula for the calculation is the following one:
•inside and outside the buildings in absence of solar irradiation:
WBGTclose environments = 0,7 tnw + 0,3 tg
•outside the building in presence of solar irradiation:
WBGTexternal environments= 0,7 tnw + 0,2 tg + 0,1 ta
where:
tnw = natural ventilation wet bulb temperature
tg= globe thermometer temperature;
ta= air temperature.
The detected data must be compared with the limit values established by the regulation; if they are
over passed, it’s necessary to:
•directly decrease the thermal stress in the considered working place;
•go on with a detailed analysis of the thermal stress.

NOTE: THE VALUES ARE STABILIZED, CONSIDERING A MAXIMUM RECTAL TEMPERATURE OF
38° C FOR THE CONSIDERED BEINGS.
To calculate WBGT index, it’s necessary that to the instrument are connected:
•HP3201.2 or HP3201 temperature probe with natural ventilation wet bulb.
•TP3276.2 or TP3275 globe thermometer.
•TP3207.2 or TP3207 wet bulb temperature probe if the detection is made in presence
of solar irradiation.
To measure WBGT index consider the following regulations:
•ISO 7726
•ISO 7243

3. USER INTERFACES
The user interface is composed of an LCD graphic back - enlighten display and start and set keys
of the instrument. With a battery power supplying without pressing any key, the back- lighting
switches off after 1 minute. To activate it again, press one key. With external power supply, the
back-lighting is always activated.
To switch the instrument on and off, press ON/OFF key. When you switch it on, the logo and the
model of the instrument will be visualize, for some seconds, then you can go to the main visualiza-
tion.

3.2 THE KEYBOARD
The instrument keys have the following functions:
ON-OFF / AUTO-OFF key
ON-OFF : it allows switching the instrument on and off.
When you switch the instrument on, the first screen will be visualized and, after some seconds, the
detected measurements will be visualized.
AUTO-OFF is on if the instrument is supplied with batteries. The instrument switches off after 8
minutes from the switching on. When you switch the instrument on, the AUTO-OFF function can
be disabled pressing together ESC and ON/OFF keys.

4. WORKING
Before switching the instrument on, connect the SICRAM probes to the inlets: 8 pin male
connector DIN 45326 that is on the bottom of the instrument.
NOTE: The probes must be connected to the instrument off. If you connect a new probe to the
instrument already switched on, it isn't recognized, so it's necessary to switch the instrument
off and switch it on again.
If you connect a probe with the instrument switched on, you have an acoustic alarm (a beep per
second) and you can visualize it on the display in correspondence of a disconnected physical size,
the “LOST” message will be visualized.
If you insert more probes of the same type, it will be only consider the first recognized probe:
the scansion of the probes, for their recognition, happens from the inlet 1 up the inlet 3.
When you switch the instrument on, on the display appears the following writing for at least 10 sec-
onds:
HD32.2 WBGT Index
Firm.Ver.=01.00
In addition to Delta Ohm logo are indicated the instrument code and the firmware version.
After connecting the probes, switch the instrument on: the display, after 10 seconds, will appear in
the measurement visualization mode:

4.1.4 Instrument setting
To set the instrument up, you enter to the main menu, pressing MENU key. For more details, see
the chapter 5.
4.1.5 Start a memorization section (Logging)
To start a Logging section, press MEM key: the key starts and stops the memorization (Logging) of
a data block that will be kept into the instrument internal memory. The frequency with which the
data are memorized is set with "Log interval" menu parameter. The memorized data between a
start and a following stop represent a measurement block.
With the memorization function on, LOG and number of logging section appears on the display; a
beep is given out during each memorization.
To finish the logging, press MEM key again.
The instrument can switch off during the logging between an acquisition and the following one: the
function is controlled by Auto_shut_off_Mode parameter. With a memorization interval less than
one minute, the instrument remains always on during the logging; with an interval of at least one
minute, it switches off between an acquisition and the following one.
