1. GENERAL CHARACTERISTICS
The HD32.1 Thermal Microclimate has been designed for microclimate analysis in the workplace;
the instrument is used to detect the necessary parameters to establish if a certain workspace is
suitable to perform certain activities.
The instrument can manage three operating programs that can be loaded by the user, according to
the measurements program and the quantities being detected.
The instrument has eight inputs for probes with SICRAM module: The probes are fitted with an
electronic circuit that communicates with the instrument. The calibration settings are memorized
inside.
All SICRAM probes, except the vane probe, can be plugged into any input: They will be
automatically detected when you turn the instrument on.
NOTE: The vane probe, complete with SICRAM module, for wind speed measurement can be
exclusively connected to input 8.
The instrument comes with a barometric pressure sensor. The barometric pressure is displayed only
by the Microclimate Analysis operating program.
The machine can be programmed to perform the logging (capture) of a measurement session. You
can specifically set a sampling interval per each session.
Furthermore, the auto-start function can be used to activate the setting of the measurements’ initial
date and time, and the automatic start and end of the data logging session.
NOTE: The set capture interval is valid for all the probes connected to the machine.
Other operating programs user selectable/settable common parameters are:
• The units of measurement for the displayed temperature quantities: °C, °F, °K.
• The system date and time
• The display of the maximum, minimum, and average statistic parameters and their
deletion.
• The data transfer speed via the serial RS232 port.
• The setting and enabling/disabling of the keyboard protection password.
The operating programs are:
• prog. A: HD32.1 Microclimate Analysis
• prog. B: HD32.1 Discomfort Analysis
• prog. C: HD32.1 Physical Quantities
The operating program A: Microclimate Analysis, HD32.1, can simultaneously detect the
following quantities:
• Globe thermometer temperature
• Natural ventilation wet bulb temperature
• Environment temperature
• Atmospheric pressure
• Relative humidity
• Wind speed
HD32.1 - 5 - V2.1
The operating program A: Microclimate Analysis displays also:
• The local turbulence intensity Tu, for DR (Draught Rating) calculation.
• The WBGT index (Wet Bulb Glob Temperature) with or without solar radiation.
• The WCI index (Wind Chill Index)
• The average radiation temperature tr.
The operating program B: Discomfort Analysis, HD32.1, can simultaneously detect the
following quantities:
• Air temperature detected at head height (1.7 m for a standing person; 1.1 m for a seated
person).
• Air temperature detected at abdomen height (1.1 m for a standing person; 0.6 m for a seated
person).
• Air temperature detected at ankle height (0.1 m).
• Temperature at floor level.
• Temperature of the net radiometer.
• Net radiation.
• Radiant asymmetry temperature.
The operating program B: Discomfort Analysis is used to calculate the local discomfort indexes
due to vertical temperature gradients or radiant asymmetry temperature.
The operating program C: Physical Quantities, HD32.1, can simultaneously detect the following
physical quantities:
• Temperature
• Relative humidity
• Illuminance, luminance, PAR, irradiance
• Wind speed
• carbon monoxide concentration CO.
• carbon dioxide concentration CO2
By using the operating program C: Physical Quantities, HD32.1 can simultaneously manage
up to six different probes complete with SICRAM module: one or two light probes and a probe for
each of the other physical quantities. If two or more probes of the same physical quantity are
connected (light probes excluded), the instrument recognizes only one probe. If, for example,
you insert two Pt100 temperature probes complete with SICRAM module to inputs 1 and 2, the
probe connected to input 1 is immediately recognized while the probe connected to input 2 is
ignored. The probe is detected during turn on, therefore if a probe is changed, it is necessary to
turn the machine off and on. During turn on the instrument performs a scan from input 1 to input 8.
The probes arrangement in relation to the inputs is arbitrary, except for the vane probes.
The vane probe, complete with SICRAM module, for wind speed measurement can be
exclusively connected to input 8.

2. WORKING PRINCIPLE
2.1 THE OPERATING PROGRAM A: MICROCLIMATE ANALYSIS
By microclimate is meant those environmental parameters that influence the heat exchange between
the person and the surrounding spaces, and that determinate the so-called " thermal well-being".
The microenvironment climatic factors, together with the type of work performed, generate a series
of biological responses linked to thermal well-being (Comfort) or uneasiness (Discomfort).
The human organism, indeed, tends to maintain a thermal balance so that the body temperature is
optimum.
The HD32.1, Thermal Microclimate, through its operating program A: Microclimate Analysis
measures the following quantities:
• tnw: natural ventilation wet bulb temperature
• tg: globe thermometer temperature
• ta: environment temperature
• pr: at mospheric pressure
• RH: relative humidity
• va: wind speed
In addition to the direct measurements performed with the probes connected, the instrument can
directly calculate and display the following well-being data:
• WBGT index
• Tu index
• WCI index
• Average radiation temperature tr
2.1.1 WBGT Index
WBGT (Wet Bulb Globe Temperature) is one of the indexes used to determine the thermal stress of
a person in a hot environment. It represents the value, related to the metabolic output linked to a
specific work activity, that causes a thermal stress when exceeded. The WBGT index combines the
measurements of the natural ventilation wet bulb temperature tnw with the globe thermometer
temperature tg and, in some situations, with the air temperature ta. The calculation formula is the
following:
• Inside and outside buildings without solar radiation:
WBG
enclosed spaces
= 0.7 tnw + 0.3 t
g
• Outside buildings with solar radiation:
WBGT
outdoor spaces
= 0.7 tnw + 0.2 tg + 0.1 ta
where:
t
nw
= natural ventilation wet bulb temperature;
t
g
= globe thermometer temperature;
t
a
= air temperature.
The measured data should be confronted with the limit values prescribed by regulations; when
exceeded you have to:
HD32.1 - 9 - V2.1
• Reduce directly the thermal stress on the workplace being examined;
• Proceed to a detailed analysis of the thermal stress.

In order to calculate the WBGT index, the following probes should be connected:
• The natural ventilation wet bulb temperature probe.
• The globe thermometer probe.
• The dry bulb temperature probe, if the measurement is performed with solar
radiation.
In order to measure the WBGT index, you should refer to the following regulations:
• ISO 7726
• ISO 7243
2.1.2 Turbulence Intensity (Tu index)

The discomfort from air current is defined as an undesired local cooling of the body due to air
mot io n. The
DR indicates the percentage of unsatisfied people due to air current. The DR index is
calculated when the temperature goes from 20 °C to 26 °C and the average wind speed is < 0.5
m/s.
The DR index is calculated using the DeltaLog10 software.
2.1.3 WCI Index
WCI (Wind Chill Index) allows a synthetic evaluation of the effects of cold environments on man.
It shows the cooling index due to the wind. It allows evaluating the discomfort perceived during
exposure to low temperatures and wind. The index does not consider the clothing and the work
intensity.
The WCI index is calculated by the instrument in presence of air under 10°C.
The WCI index calculation formula is:
WCI = 13.12 + 0.6215 t
a
– 11.37 v

+ 0.4275 ta v
a
0.16
where:
t
a
: air temperature (in °C);
v
a
: Wind speed (in km/h) calculated at 10 m from the ground.
As the instrument measures the wind speed at 1.5 m from the ground, the formula is corrected as
follows:
WCI = 13.12 + 0.6215 t
a
– 11.37(1.5 v
1.5
)
0.16
+ 0.4275 ta (1.5 v

where v

is the wind speed measured by the instrument at 1.5 m from the ground.
The following tables report some WCI values and the relevant frostbite risks (source: NOAA –
National Weather Service).

a
.
• The hot-wire probe for wind speed measurement.
In order to measure the WCI index, refer to the following:
• ISO 7726
• NOAA Specifications, National Weather Service.
2.1.4 Average Radiation Temperature tr
The average radiation temperature is defined as the temperature of a thermally uniform simulated
environment that would exchange with a man the same thermal radiation power exchanged in the
real environment.
In order to evaluate the average radiation temperature you have to measure: The globe
thermometer temperature, the air temperature and the wind speed measured near the globe
thermometer. The average radiation temperature calculation formula is the following:

The average radiation temperature does not correspond to air temperature: If within a room very
high temperature surfaces are present (for example, a fireplace), these hot areas remarkably
influence the average radiation temperature.
The average radiation temperature is detected with the globe thermometer. A temperature probe
formed by a 150 mm copper ball, painted black matt, with emissivity equal to ε
g
= 0.95 (according
HD32.1 - 12 - V2.1
to ISO 7726), and a Pt100 sensor inside. The globe thermometer temperature could be remarkably
higher than the air temperature. For example in a mountain cottage, in which air is at 0°C but the
presence of a fireplace produces an average radiation temperature of 40°C, ensuring a comfortable
condition. In normal conditions, maintaining a certain difference between average radiation
temperature and air temperature (where
T
MR
is remarkably higher than TA) is preferable in order to
get a better environment quality. In houses, where fireplaces and ranges are absent, generally the
average radiation temperature is equal to the air temperature, or even lower. These conditions
(mainly in buildings with large window surfaces) are not particularly healthy as the warm humid air
facilitates the development of pathogenic organisms. From this point of view, using lamps or
radiating panels is more healthy. It is much more hygienic to use a higher average radiation
temperature than the air temperature, in order to guarantee comfort conditions. The regulations use
air temperature and not average radiation temperature to assess heating system, but this is wrong.
In order to calculate the average radiation temperature you have to connect the following
probes:
• Globe thermometer probe
• Air temperature measurement probe
• Hot-wire probe for wind speed measurement
In order to measure the average radiation temperature, you should refer to the following
regulations:
• ISO 7726
HD32.1 - 13 - V2.1
2.2 THE OPERATING PROGRAM B: DISCOMFORT ANALYSIS
The HD32.1, Thermal Microclimate, through its operating program B: Discomfort Analysis,
measures the following quantities.
•
t
h
head temperature: air temperature detected at head height
•
tb: body temperature: air temperature detected at abdomen height
•
tk: ankle temperature: air temperature detected at ankle height
•
tf: floor temperature: air temperature at floor level
•
P: net radiation: net radiation, measured in Wm
-2
.
By knowing the temperatures at head t
h
, abdomen tb, ankles tk and floor t
f
height, you can
determine, according to
ISO 7730, the following local thermal discomfort indexes:
•
Unsatisfied with the vertical difference of temperature;
•
Unsatisfied with the floor temperature;
•
Unsatisfied with the radiant asymmetry.
2.2.1 Unsatisfied with the vertical difference of temperature
By detecting the temperatures at various heights you can check the presence of a air temperature
vertical gradient. This gradient could cause a local discomfort feeling. In the following figure you
can see the percentage value of the
unsatisfied with the vertical difference of temperature PD
v
,
according to the temperature gradient between head (1.10 m) and ankles (0.10 m) for a seated
person.
This index is calculated using the DeltaLog10 software.
In order to calculate the PDv index (unsatisfied with the vertical difference of temperature)
you have to connect the following probes:
• Probe for the air temperature detected at head height
• Probe for the air temperature detected at ankle height
The PDv index is calculated by the DeltaLog10 software.
In order to calculate the PDv index (unsatisfied with the vertical difference of temperature)
you should refer to the following regulations:
• ISO 7730
HD32.1 - 14 - V2.1
2.2.2 Unsatisfied with the floor temperature
By measuring the floor temperature you can calculate the
percentage index of the unsatisfied with
the floor temperature. The following diagram shows the PD
f
index trend according to the floor
temperature.
In order to calculate the PDf index (unsatisfied with the floor temperature) you have to
connect the following probe:
• Floor temperature probe
The PDf index is calculated by the DeltaLog10 software.
In order to calculate the PDf index (unsatisfied with the floor temperature) you should refer
to the following regulations:
• ISO 7730
2.2.3 Unsatisfied with the radiant asymmetry
The radiant temperature asymmetry Δt
pr
is the difference between the radiant temperatures
measured with the net radiometer. The index of the unsatisfied with the radiant asymmetry is
calculated according to a vertical (ceiling-floor) or horizontal (wall-wall) asymmetry. Form the
radiant temperature Δt
pr

reports.
6.1.1 Warnings, care and maintenance of the probes
•
Do not expose the probes to gases or liquids that could corrode the material of the probe. Clean
the probes carefully after each measurement.
•
Do not bend the probe connectors or force them upward or downward.
•
Comply with the correct polarity of the probes.
•
Do not bend or force the contacts when inserting the probe connector into the instrument.
•
Do not bend, deform or drop the probes, as this could cause irreparable damage.
•
Always select the most suitable probe for your application.
•
To obtain reliable measurements, temperature variations that are too rapid must be avoided.
•
Some probes are not insulated from their external casing; be very careful not to come
into contact with live parts (above 48V). This could be extremely dangerous for the
instrument as well as for the operator, who could be electrocuted.
•
Avoid taking measurements in presence of high frequency sources, microwave ovens or large
magnetic fields; results may not be very reliable.
•
The instrument is water resistant, but should not be immersed in water. Should the instrument
fall into the water, check for any water infiltration.
Wind speed hot-wire sensor AP3203
•
The wind speed hot-wire sensor AP3203 is heated and, in the presence of gas
vapors, could trigger a fire or explosion. Do not use the probe in the presence of
inflammable gases. Ensure that no potentially explosive gas or vapor leakage is
present in the measurement environments.
•

6.2 PROBES FOR THE OPERATING PROGRAM C: PHYSICAL QUANTITIES
6.2.1 Temperature measurement using the probe Pt100 complete with SICRAM module
The instrument works with temperature probes fitted with the SICRAM module (with a Platinum
Pt100 sensor with 100Ω resistance at 0°C). The excitation current was chosen in order to minimize
the sensor self-heating effects. The SICRAM module acts as an interface between the sensor on the
probe and the instrument. There is a microprocessor circuit with a permanent memory inside the
module that enables the instrument to recognize the type of probe connected and to read its
calibration information.
Upon turning on the instrument automatically detects the probes fitted with SICRAM module:
The probes are detected during turn on, and this cannot be performed when the instrument is
already on, therefore if a probe is connected and the instrument is on, it is necessary to turn it
off and on.
In all versions the temperature sensor is housed in the end part of the probe.
The response time for the measurement of the temperature in air is greatly reduced if the air is
moving. If the air is still, stir the probe back and forth. The response times are longer than those for
liquid measurements.
The temperature measurement by
immersion is carried out by inserting the probe in the liquid for at
least 60mm; the sensor is housed in the end part of the probe.
In the temperature measurement by
penetration the probe tip must be inserted to a depth of at least
60mm, the sensor is housed in the end part of the probe. when measuring the temperature on frozen
blocks it is convenient to use a mechanical tool to bore a cavity in which to insert the tip probe.
In order to perform a correct
contact measurement, the measurement surface must be even and
smooth, and the probe must be perpendicular to the measurement plane. A contact measurement is
hard to perform due to various factors: The operator must be experienced in handling the probe and
consider all the factors influencing it.
So as to obtain the correct measurement, the insertion of a drop of oil or heat-conductive
paste is useful (do not use water or solvents). This method improves the response time, in
addition to accuracy.
The °C or °F unit of measurement can be chosen for display, printing, and logging.
The sensor is calibrated in the factory, and the Callendar Van Dusen parameters are recorded
in the SICRAM module.

6.2.3 Measurement of relative humidity using the combined humidity/temperature probe
The instrument works by using combined humidity/temperature probes (temperature with Pt100
sensor). The combined humidity/temperature probes are fitted with SICRAM module that acts as an
interface between the sensor on the probe and the instrument. There is a microprocessor circuit with
a permanent memory inside the module that enables the instrument to recognize the type of probe
connected and to read its calibration information.
The probes are detected during turn on, and this cannot be performed when the instrument is
already on, therefore if a probe is connected and the instrument is on, it is necessary to turn it
off and on
.
Measurement of relative humidity
The humidity probes are humidity/temperature combined probes: The humidity sensor is a
capacitive type sensor, the temperature sensor is a Pt100 (100Ω at 0°C).
The instrument measures relative humidity %RH and temperature, and starting from the fixed
barometric pressure value of 1013.25mbar it calculates the following resulting quantities:
•
g/kg Grams of vapor in a kilogram of dry air
•
g/m
3
Grams of vapor in a cubic meter of dry air
•
hPa Partial vapor pressure (hPa)
•
J/g Enthalpy
•
Td Dew point (°C or °F)
•
Tw Wet bulb temperature (°C or °F)
A measurement is performed by placing the probe in the area of whose parameters you wish to
measure. Keep the probe far from elements that might interfere with measurement such as: heat or
sources of cooling, walls, air-streams, etc. Avoid temperature drops that might cause condensation.
A reading taken when no heat drop occurs is practically immediate. In contrast, in conditions
involving heat drops, it is necessary to wait until the sensors and their housing have reached a
thermal equilibrium in order to prevent heat irradiation or absorption on the relative humidity
sensor, which would cause a faulty measurement. Since temperature affects relative humidity; move
the probe like a fan in order to speed the response time in the presence of heat drops.
The calibration of the humidity/temperature sensor by the user is not required.
The humidity sensor is calibrated in our laboratory at 23°C at the points of 75%RH, 33%RH
and 11.4%RH. On request, the probes can be checked at different isotherms.
The temperature sensor is calibrated in the factory and the Callendar Van Dusen parameters
are recorded in the SICRAM module.

6.2.5 Wind speed measurement
The instrument works with hot-wire and vane probes fitted with the SICRAM module.
The SICRAM module acts as an interface between the sensor on the probe and the instrument.
There is a microprocessor circuit with a permanent memory inside the module that enables the
instrument to recognize the type of probe connected and to read its calibration information.
Note: The vane probes can be exclusively connected to input 8.
The probe is detected during turn on, and this cannot be performed when the instrument is
already on, therefore if a probe is connected and the instrument is on, it is necessary to turn it
off and on
.
The AP471 and AP472 series probes measure the incident wind speed and flow rate; some also
measure air temperature. The hot-wire measurement principle is used for the AP471 series and the
vane principle for the AP472 series. On request, the probes of the AP471 series can be fitted with a
telescopic rod that eases measurements in areas difficult to reach (for example vents).
The typical applications are wind speed and flow rate checks in air conditioning, heating and
cooling systems, or environmental comfort determination, etc.
In addition, the measured fluid temperature must be considered: the probes measure air flows at
80°C maximum temperature.
The measurements provided by the instrument using the probes are: wind speed, flow rate, and air
temperature.
The following units of measurement are available:
•
for wind speed: m/s - km/h - ft/min - mph (miles/hour) - knots;
•
for air temperature: °C and °F;
•
for flow rate: l/s (liters/s) - m

Care and maintenance of the probes
The speed sensor of the AP471 S… probes is heated and,
in the presence of gas vapors,
could trigger a fire or explosion. Do not use the probe in the presence of
inflammable gases. Ensure that no gas or explosive vapor leakage is present in the
measurement environments.
The probe is very delicate and should be handled with extreme care. Even a simple collision,
especially of the omni directional probes that have an uncovered sensor, could render the probe
unusable. After measurement, the sensor set on the probe head must be protected with the supplied
metallic screen or threaded cylinder. During use, the AP471 S4 omni directional probe must be
protected with the special metallic grid. During transportation, the sensor must be closed into a
cylinder screwed on the end part of the probe.
Do not let fingers touch the sensors. Use only distilled water to clean the probe.

6.2.8 AP472S… Vane wind speed measurement probes complete with SICRAM module
The AP472 S1 and AP472 S2 vane probes measure the incident wind speed and flow rate. The
probe AP472 S1 measures also the temperature using a thermocouple of type K. On request, they
can be fitted with a telescopic rod that eases measurements in areas difficult to reach (for example
vents). The probes' speed and temperature measurement ranges are outlined in the table below:

Greater diameters are suitable for flow measurements in the presence of turbulence with mediumlow air speeds (i.e. at the exit of the ducts). Lower diameters are suitable in applications where the
probe surface must be much slower than the duct cross section within which the measurement is
carried out, i.e. ventilation ducts.
Calibrations
The AP472 S1 and AP472 S2 probes are calibrated in the factory; no calibration is required by the
user.
Operation
Where present, extend the telescopic rod to the necessary length
paying attention to the cable so
that it can slide freely and without strain.
Introduce the probe in the air flow being measured, maintaining the arrow at the top of the probe
parallel to the flow as indicated in the following figure.

The probe should be maintained orthogonal to the flow and not tilted in relation to it:
OK NO
The probe is correctly positioned in relation to the air-flow when the value measured is the
maximum possible.
Proceed with measurement following the instructions provided in this chapter.
Care and maintenance of the probes
The probe performance, mainly at low speeds, largely depends on the very slow friction of the vane
on its own axis. In order not to compromise this characteristic, it is recommended that forcing is
avoided, as well as blocking or rotating the vane with the fingers, and if possible, avoid inserting it
in air flows that could soil the probe.

6.2.10 Light measurement
The instrument works with probes of the LP471… series: These are photometric and radiometric
probes that measure
illumination (LP471 PHOT), irradiance (LP471 RAD, LP471 UVA, LP471
UVB and LP471 UVC),
PAR (LP471 PAR) and luminance (LP471 LUM 2). All the probes,
except the LUM 2, are provided with a diffuser for cosine correction.
Upon turning on the instrument automatically detects the probe connected to the input: It is
sufficient to connect it. If the instrument is already on, turn it off and back on again in order for the
probe to be detected. The unit of measurement is determined according to the probe connected to
the input: In cases where more than one unit of measurement is provided for the same probe, use the
UNIT key to select the one desired.
All probes are calibrated in the factory; no calibration is required by the user.
The probe is detected during turn on, and this cannot be performed when the instrument is
already on, therefore if a probe is connected and the instrument is on, it is necessary to turn it
off and on.

6.2.12 HD320A2 probe for the measurement of CO Carbon monoxide
HD320A2 probe measures the carbon monoxide concentration in air. It’s a colorless, odorless gas,
lighter than the air and it can cause explosions or fires. It is poisonous even in low quantities:
indeed, it’s sufficient a concentration of 10-30ppm of carbon monoxide in air to produce symptoms
of poisoning and about 2000ppm are fatal in less than 30 minutes.
Carbon monoxide is formed when substances containing carbon are burned in absence of oxygen,
or when, although the amount of oxygen is sufficient, the combustion occurs at high temperature,
e.g. in car engines.
Carbon monoxide is one of the major pollutant agents in urban areas. Moreover, being odorless, is
an insidious poison.
Together with the HD320B2 probe, the HD320A2 probe allows analyzing and monitoring the air
quality in internal environments and detecting any loss of CO.
The sensor for the measurement of CO consists of an electro - chemical cell with two electrodes.
CO probe calibration
The probe is calibrated by the company and, usually, doesn’t request any intervention by the user.
However, there is the possibility to make a new calibration that corrects the sensor zero:
•
in clean air (outside the CO concentration is less than 0,1ppm)
•
With the help of nitrogen cylinders (code MINICAN.12A).
CO zero calibration in clean air:
1. Place the instrument in an environment with clean air (outside, far from the companies or
the streets, the CO concentration is less than 0.1ppm), switch the instrument on and wait at
least 15 minutes till the measurements becomes stable.
2.
Press SHIFT FNC key: the shortcut window appears. With ▲▼ arrows select “cal CO”
and confirm with ENTER.
3.
The screen for the operation to do on the sensor appears (calibration or replacement):

6.2.13 HD320B2 probe for the measurement of CO2 carbon dioxide concentration
HD320B2 probe measures the carbon dioxide concentration in air. It’s indicated for checking and
monitoring the indoor air quality.
Typical applications are the check of the air quality in all the buildings where there is a crowd of
people (schools, hospitals, auditoria, canteens, etc.), in the working places to optimize the comfort.
CO
2
measurement is obtained with an infrared special sensor (NDIR technology: Non-Dispersive
Infrared Technology) that, thanks to the use of a double filter and a special measurement technique,
warranties precise, stable and long-term measurements. The air to check is spread inside the
measurement chamber through the protection membrane placed at the top of the probe.
CO2 probe calibration
The probe is calibrated by the company and usually doesn't request any intervention by the user.
However, there is the possibility to execute a new calibration that corrects the sensor offset:
•
at 400ppm in clean air
•
at 0ppm with the help of nitrogen cylinder (code MINICAN.12A).
The instrument can automatically recognize the mode of the started calibration: if 400ppm or 0ppm.
The calibration has to be done on one point: each new calibration cancels the previous one.
The concentration of carbon dioxide in air is influenced by different factors: the human activities
(companies, pollution, combustion, etc.) cause an increase of this percentage in air. The calibration
value is equal to 400ppm and it’s in clean air, for example in the country far from the more polluted
areas.
Go on as indicated below:
1. If you want to calibrate around 400ppm, make sure to apply clean air to the instrument
through a membrane placed on the head of the probe.
2.
For the calibration at 0ppm, remove the cap placed at the base of the probe in order to
discover the plug of the calibration gas inlet and connect the tube coming from the nitrogen
cylinder. Adjust the fluxmeter of the cylinder on the flow from 0.3 to 0.5l/min.
3.
Switch the instrument on and wait for at least 15 minutes before going on.
4.
Press SHIFT FNC key: the shortcut window appears. With ▲▼ arrows select “cal CO2”
and confirm with ENTER.
5.
Supply CO
2
for at least 2 minutes in order that the measurement becomes stable.
6.
Going on supplying CO
2
to the probe, press F2 = CAL CO2 function key: the calibration,
which lasts three minutes, starts. In this phase the instrument measures CO
2
and calibrates
itself to a value next to 0ppm if you are using the nitrogen cylinder, at 400ppm if you are
calibrating it in clean air.
HD32.1 - 95 - V2.1
7. Wait for three minutes necessary for the calibration without modifying the working
conditions.
8.
If the timer reaches the zero, the instrument gives an acoustic signal out that confirms that
the calibration is finished.
Note: the instrument rejects the calibration values that exceed ±150ppm from the theoretic
value.
HD32.1 - 96 - V2.1
7. SERIAL INTERFACE AND USB
The HD32.1 is fitted with an electrically isolated RS-232C serial interface, and an USB 2.0
interface. Optionally, they can be connected using a serial cable with sub D 9-pole female
connectors (code
9CPRS232) and a cable with USB 2.0 connectors (code CP22).
The USB connection requires the previous installation of a driver included in the DeltaLog10
software package.
Install the driver before connecting the USB cable to the PC (follow the
instructions included in the software package).
Standard parameters of the instrument RS232 serial transmission are:
•
Baud rate 38400 baud
•
Parity None
•
N. bit 8
•
Stop bit 1
•
Protocol Xon/Xoff
It is possible to change the RS232C serial port baud rate by setting the "
Selection of the serial
transmission speed (Baud Rate)" parameter in the menu (please see the menu on chapter 5.3.1 The
Baud Rate). The possible values are: 38400, 19200, 9600, 4800, 2400, 1200. The other
transmission parameters are fixed.
The USB 2.0 connection does not require the setting of parameters (Baud rate = 460800 fixed).
The selection of the port is carried out directly by the instrument: If the USB port is
connected to a PC, the RS232 serial port is automatically disabled, and vice versa.
The instruments are provided with a complete set of commands and data queries to be sent via the
PC.
All the commands transferred to the instrument must have the following structure:
XXCR where: XX is the command code and CR is the Carriage Return (ASCII 0D)
The XX command characters are exclusively upper case characters. Once a correct command is
entered, the instrument responds with "&"; when any wrong combination of characters is entered,
the instrument responds with "?".
The instrument response strings end with the sending of the CR command (Carriage Return) and LF
(Line Feed).
Before sending commands to the instrument via the serial port, locking the keyboard to avoid
functioning conflicts is recommended: Use the P0 command. When complete, restore the keyboard
with the P1 command.
