LogBox-DA
ELECTRONIC DATA LOGGER − MANUAL V1.1x J
PRESENTATION
LogBox-DA is an electronic data logger with two input channels: one
analog and one digital. The values measured by these channels
(data) are stored in the logger electronic memory and later sent to a
computer in table or graphical form. It is possible to export them for
use in programs such as spreadsheets.
To configure the logger and view or download data, you must use the
NXperience software. When you configure it, you can set the start
and end mode of the recordings, the parameters of each input,
among other functions.
LogBox-DA provides an auxiliary electronic switch, which can be
used in series with the power supply of external instruments,
connected to the logger. With this feature, you can configure the
logger to close the switch and power these instruments only at the
instant of acquisition, extending the battery life of the external
instrument.
MEMORY CAPACITY
64 k Model: It allows up to 64,000 logs,
•
The memory capacity is divided between the enabled channels.
When there are two enabled channels, each has half of the available
memory. When a single channel is enabled, it has all the memory at
its disposal.
The available memory capacity is indicated on the identification label,
attached to the housing of the logger:

INPUT SIGNALS
Channel 1 (IN 1) counts digital electrical pulses, which can be of the
following types: Voltage Pulse, Dry Contact (switch) or Open
Collector, according to the configuration made.
Channel 2 (IN 2), in turn, measures analog electrical signals, which
can be of the following types: 0-20 mA, 4-20 mA, 0-50 mV, or 0-5 V,
according to the configuration made.
Note: For the channel 2, in addition to performing the configuration
via software, you must properly position the internal jumper.

DATA ACQUISITION (LOGGING)
Data can be acquired by means of two different modes.
For channel 1, which counts electrical pulses, the recorder counts the
number of pulses received in a programmed period. At the end of
each period, the measured count value is stored in the memory of
the logger, creating a log. The maximum number of logs that can be
stored depends on the memory capacity.
For channel 2, the logger can: 1) Perform a single measurement
within a defined period and log the value read or 2) perform ten
measurements in this period and log in memory the average of the
values read or log the minimum value or maximum value measured.
OPERATION
In the NXperience software, which must be previously installed on
the computer to be used, you can configure logger operation mode
(see
LOGGER CONFIGURATION
configuration, you must use the IR-LINK3 Communication Interface
(see
IR-LINK3 OPTICAL INTERFACE
Once the device has been configured and the electrical input
connections have been made, it is ready to measure and log the
signals applied to the input channels. Status indicators display the
current condition of the logger.
STATUS INDICATORS (LEDS)
The Status Indicators (see Figure 2), located on the front of the
logger, serve to indicate the current operating condition of the device:
LOG Indicator (Logging): If it is waiting to begin acquisitions
(stand-by) or after a series of acquisitions has been completed, the
LED blinks once every four seconds. If it is performing acquisitions,
it blinks twice every four seconds.
AL Indicator (Alarm): This indicator informs about alarm
situations. Whenever an alarm situation occurs, it blinks once
every four seconds. It remains in this condition until a new setting
is applied to the logger.
