1. GENERAL FEATURES HD32.3 is designed for: • Analysis of hot environments through WBGT index (Wet Bulb Globe Temperature) in presence or absence of solar radiation. • Analysis of moderate environments through PMV index (Predicted Mean Vote) and PPD index (Predicted Percentage of Dissatisfied). The instrument is provided with three inputs for probes with SICRAM module: the probes have an electric circuit that communicates with the instrument; the sensor calibration data are saved in its permanent memory.

1. Inlets for SICRAM probes. 2. Inlet for power supply. 3. Back - enlightened graphic display. 4. Navigation key ▲: it allows the navigation through the menus. During the normal working it selects the reset of statistic data. 5. ESC key: it allows exiting from the menu or, in case of a submenu, exiting from the current level display. 6. Navigation key ◄: it allows the navigation through the menus. During a normal visualization, it allows to visualize the statistic data: maximum, minimum and medium. 7.
2. WORKING PRINCIPLE Microclimate term means the environmental parameters that influence the thermal exchanges between 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 influences a series of your biologic responses connected to well-being situations (Comfort) or thermal uneasiness (Discomfort).
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.
From PMV comes a second index called PPD (Predicted Percentage of Dissatisfied) which calculates in percentage the “dissatisfied” beings in relation with precise microclimatic conditions.

Measurement In the place where you want to measure, you must assembly the tripod and the probes necessary for the measurement. You set the instrument up and then you start measuring. If the measurement has to be done in other places, you have to move all the equipment in the new measurement position. At the end of the measurement or after some times, the acquired data are transferred to the PC for the elaboration and to allow writing the measurement report/s. 6.1.

7.1 THE DATA MEMORIZATION AND THE DATA TRANSFER TO A PC HD32.3 can be connected to RS232C serial port or USB port of a PC and can exchange data and information through DeltaLog10 software that works with Windows. The values measured can be printed (ENTER key) or stored in the memory of the instrument by using the Logging function (MEM key). The memorized data can be transferred to the PC in a second time. 7.1.
9. INSTRUMENT SIGNALS AND FAULTS The following table lists all error indications and information displayed by the instrument and supplied to the user in different operating situations: Display indication Explanation ---.-- This appears if the sensor relevant to the indicated physical quantity is not present or is faulty OVFL Overflow appears when the probe detects a value that exceeds the expected measurement range.
10. BATTERY SYMBOL AND BATTERY REPLACEMENT – MAIN POWER SUPPLY The battery symbol On the display constantly shows the battery charge status. To the extent that batteries have discharged, the symbol "empties". When the charge decreases still further it starts blinking. In this case, batteries should be replaced as soon as possible. If you continue to use it, the instrument can no longer ensure correct measurement and turns off. Data stored on memory will remain.
11. INSTRUMENT STORAGE Instrument storage conditions: • Temperature: -25…+65°C. • Humidity: less than 90% RH without condensation. • During storage avoid locations where: • humidity is high; • the instrument may be exposed to direct sunlight; • the instrument may be exposed to a source of high temperature; • there are strong vibrations; • there are steams, salt or any corrosive gas. Some parts of the instrument are made of ABS plastic, polycarbonate: do not use any incompatible solvent for cleaning. HD32.
