Bulletin DA-UDL

The Series UDL Universal Input Data Loggers are available with 0, 2, or

4 universal inputs. Each universal input can be individually configured to
accept a thermocouple, RTD, thermistor , voltage, or current input. All Series
UDL data loggers have an internal temperature sensor and a digital input
which can be used as a trigger to start logging or as a pulse counter for inter­facing with flow meters or other sensors with a pulse output. Optional fea­tures include an internal humidity sensor, an LCD display, and an external
humidity and temperature sensor. The Series UDL loggers interface to the
USB port of a PC. The unit includes software, USB connection cable and
installed battery .

T o issue the logger, from the Logger Operations menu select UDL Network.

In the Explorer window that comes up, RIGHT CLICK on the device icon and
select Configure.

Enter relevant parameters within the General, Input Setup, Manifest T ext, and
Input T rim buttons on the left. Click the Issue button when complete.

NOTICE

Issuing the parameters erases all data currently stored in the logger.

INITIAL SETTING

The first time a logger is set, you will be prompted to enter an Owners Manifest
and a Passcode. This is the only time you will be asked for this information
and it cannot subsequently be changed.

Owners Manifest is a label for the logger normally used to record details of
the owner and/or details related to the logger such as date purchased, ship­ment, application, etc. (256 characters).

If the default Passcode is changed, and if it is lost, not even the factory can
retrieve it. If this happens then the logger cannot be issued ever again. It is
recommended that the Passcode NOT be changed.

External Power Supply (Optional)

Having selected the correct sensor type, the appropriate connections can
be made. The type of sensor used must be selected via the software prior
to issue.

The inputs are isolated from the communications port but not from each
other . Care should be taken to avoid gr ound loop pr oblems.

CONFIGURATION

Once a password has been entered, the Configuration window will come up.

NOTICE

Whenever a new type of data logger is connected to the PC, the correct data
logger will have to be selected from the Configuration window. From the
Options menu, select Configuration to bring up the Configuration window.

DOWNLOAD DATA

Download data by connecting the logger to the PC.

From the Logger Operations menu select UDL Network.

In the Explorer window that comes up, RIGHT CLICK on the device icon and
select Download. Data is then presented graphically . At this stage, data can
be saved to the computer .

GENERAL BUTTON
Location allows a 12 character description to be entered.

Data T ypedefines the value that is stored to memory .

Point is when every sampled measurement is stored directly to memory.

Averaging is the average value per period stored.

Maximum is the maximum value per period stored.

Minimum is the minimum value per period stored.

Read Rate is the rate at which the sampling points are measured, or the

period.

Log Interval is the time between when the sample points are stored.

Display Update is how often the LCD updates. This also defines the flash

rate of the LEDs, so setting it to a longer interval will improve battery life.

Stop when Full means that when the logger’ s memory is full it will stop log­ging.

Wrap when Full means that when the logger’s memory is full, it will over­write the oldest data and continue to log.

In the Graph tab, choose the desired temperature units and other graph
options.

In the Device tab, select the correct logger by clicking the button displaying
the device icon matching the logger you are using.

Log Size sets the effective memory size in readings per channel. The Default
option sets the memory size to the maximum available, while the Custom
option means that a smaller maximum memory can be set.
