LogBox-RHT-LCD
TEMPERATURE AND HUMIDITY LOGGER – INSTRUCTIONS MANUAL V2.0x A

PRESENTATION
LogBox-RHT-LCD
is an electronic temperature and relative
humidity logger. Sensors measure these quantities and the values
obtained are visualized on the LCD display and stored in electronic
memory. The stored data is later sent to a computer, which allows it
to be viewed and analyzed in the form of tables or graphs. It is
possible to configure the humidity output to display the measured
Relative Humidity
value or the
Dew Point
temperature value.
The
NXperience
software is the tool used to set up the device and
view the data downloaded by the logger. Parameters such as
acquisition start and end times and intervals between acquisitions, for
example, can be easily configured through the
NXperience
software.
The data acquired by the logger can be exported for analysis in other
programs, such as spreadsheet programas.

IDENTIFICATION
The identification label is attached to the logger housing. Verify that
the characteristics described on this label are in accordance with
what was requested. The
RHT-LCD
model measures temperature
and relative humidity.
The following elements are shown in the logger front:
Figure 1 –
Logger Front
START / STOP button
: Button that can be configured to start or
stop acquisitions. When pressed, it also used to navigate or change
screens.
Status Indicator (LOG)
: This indicator will be active when the
logger is performing acquisitions and will be deactivated when the
acquisitions are finished or while they are not started.
Alarm Indicator (AL1 and/or AL2)
: This indicator informs you of
alarm situations that have occurred and will be active whenever an
alarm situation occurs. It will remain in this condition until a new
configuration is applied to the logger.
IR Communication Window (COM)
: This indicator is activated
when a communication attempt is made or when communication
between the logger and the computer is established.
