LogBox-RHT-LCD
TEMPERATURE AND HUMIDITY LOGGER – INSTRUCTIONS MANUAL V1.1x C
1 PRESENTATION
LogBox-RHT-LCD is an electronic logger of temperature and
relative humidity. There are sensors that measure such data and
values (data) obtained are displayed in an LCD screen and stored in
an electronic memory. Data can be later viewed and analyzed on a
PC where they can be opened in tabular and graphical forms. The
humidity output can be configured to display Relative Humidity
values or the temperature value of Dew Point.
The logger is supplied with LogChart II software, which enables to
set up the logger operation mode. It is also used for visualization of
collected data. Other parameters such as end of measurements,
logging interval, etc., are easily defined through the LogChart II
software.
Measurements can be exported to and opened in other applications,
such as spreadsheet programs.
1.1 Identification
The identification label is on the logger body. Check if the features
described are in accordance with your order. The RHT-LCD model
is designed to measure temperature and relative humidity.
The following elements are shown in the logger front:
Fig. 1 – Logger Front
START / STOP button: Can be configured to start or stop logging
when pressed. It can also be used to browse and change screens.
Status indicator (LOG): Indicates when the device is logging.
Note: When logs are finished or not started, the indicator remains
deactivated.
Alarm Indicator (AL1 and/or AL2): Warns the user as to alarm
conditions. It remains active whenever an alarm condition occurs,
until a new configuration is applied to the logger.
IR Communication Window (COM): Activated when there is a
communication attempt or when communication between logger and
PC is activated.
