I

NTRODUCTION

 

The

 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 

NXperience

 and the 

LogChart

 

II

 configurator software are the tools used to configure the operating mode and to view the downloaded 

data. Parameters such as start and end times of logs and log interval, for example, are easily defined through the 

NXperience

 and the 

LogChart II

 software. 

Measurements can be exported to and opened in other applications, such as spreadsheet programs. 

3.1

 

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: 

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. 

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.
