3. USER INTERFACE
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

model of the instrument will be visualized, for some seconds, then you can go to the main visualiza-
tion.
3.1 THE DISPLAY
HD32.3 visualizes the parameters for the calculation of WBGT index and for the calculation of
PMV-PPD indexes. During the normal working, pressing the key you can go from the visualiza-
tion of WBGT index parameters to the PMV – PPD index parameters visualization.
Visualization of WBGT Index:
WBGT Index
2008/11/28 08:00:00
Log 00 00:00:00
Tn 15.6 °C
Tg 20.2 °C
T 20.2 °C
WBGT(in) 17.0 °C
WBGT(out) 17.0 °C
The first line visualizes the charge condition of the battery, the second line indicates the current
date and the current hour. If logging function is activated, the third line indicates the current log-
ging number and the spent time from the logging start.
The detected sizes are:
Tn: wet bulb temperature with natural ventilation
Tg: globe thermometer temperature
T: ambient temperature
WBGT (in): WBGT index in absence of direct solar irradiation
WBGT (out): WBGT index in presence of direct solar irradiation
Pressing the key you can visualize the PMV-PPD index:
