4 OPERATION
Before switching the instrument on, connect the probes to the inputs
.
•
For the measurement of the
WBGT
index, connect the following SICRAM probes:
o
TP3207.2
or
TP3207
dry bulb temperature probe.
o
TP3276.2 or TP3275 globe thermometer probe.
o
HP3201.2 or HP3201 or TP3204S natural ventilation wet bulb temperature probe.
•
For the measurement of the
PMV/PPD
indices and mean radiant temperature
T
r
, connect
the following SICRAM probes:
o
HP3217.2R
or
HP3217R
temperature and relative humidity combined probe.
o
AP3203.2 or AP3203 omnidirectional hot wire air speed probe.
o
TP3276.2 or TP3275 globe thermometer probe, one of the following:
•
For the measurement of the
TU/DR
indices, connect the
AP3203.2
or
AP3203
omnidirec-
tional hot wire air speed SICRAM probe.
•
For the measurement of the CO
2
carbon dioxide, connect the HP3217B4 SICRAM probe or
connect to the RS485 port the PMBsense-M probe.
•
For the measurement of the PM1.0 - PM2.5 - PM10 particulate matter, connect to the RS485
port the
PM[B]sense-M probe.
Notes:
1) The probes must be connected when the instrument is off. If a probe is connected
when the instrument is already on, it is not recognized: it is necessary to switch the
instrument off and on again.
2) If a probe is disconnected when the instrument is on, an acoustic alarm will be heard (a beep
per second) and the “LOST” message will be displayed in correspondence of the disconnected
physical quantity.
3) If more probes of the same type are connected, it will be considered only the first recognized
probe: the scan of the probes, for their recognition, starts from input A.
To switch the instrument on and off, press the ON/OFF key.
When the instrument is switched on, the instrument model and the firmware revision (at the
bottom left) will be displayed for some seconds, then the measurements are displayed.
If multiple measurement screens are available, use the "left arrow" key on the display to switch
from one screen to another. The scrolling is cyclic.
The various measurement screens are illustrated below (the screens actually visible depend on
the instrument measurement settings, see the MENU chapter).
