Series BDL Button Data Logger

Specifications - Installation and Operating Instructions

The Series BDL Button Data Logger records temperatures and humidi-

ty in applications where size and cost effectiveness are key. The BDL is housed
in a stainless steel case and is water resistant, making it durable in hostile
environments where excessive moisture is present. The BDL is self-powered
and features a USB interface. Sample rate and high/low alarms are user
selectable through the Windows®-based application. The included software
displays downloaded data graphically with trace and zoom functions. The
logger is very small which enables it to be inserted into small items and pack­ages. The Series BDL-K Logger Kit includes 2 buttons, 2 magnets, an inter­face cable, and a plastic button holder.

CONFIGURATION

The first time the software is opened a password will need to be entered.
Once a password has been entered, the Configuration window will come up.

After the initial launch of the software, 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

Connect the button adapter to the PC.

Insert the Series BDL into the button adapter, and from the Logger Operations
menu, select Read Logger.

Data is then presented graphically. At this stage, data can be saved to the
computer.

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.

Set up the logger by inserting the Series BDL Button Data Logger into the
button adapter and connecting the adapter to the PC.

From the Logger Operations menu, select Issue Logger to bring up the Issue
Window. Enter the relevant parameters into the operating software such as
sample rate, alarm parameters, etc.

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.

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.

ALARMS

Within the Issue Window, click the Alarm/LED Blink tab to enter the high and
low Alarm Set Points. The high and low Alarm Delays state how long the log­ger has to be in an alarm state before it is registered as an alarm.

The alarms are armed the first time the temperature is in a non-alarm range.
However, if Delayed Start is enabled, then the alarms are armed as soon as
it starts logging on the specified date and time.

LOGGER NAMING/LABELING

Within the Issue Window, click the Manifest Text tab. The User Manifest is a
label for the logger that takes up to 450 characters and can be changed every
time the logger is set.

The Owner Manifest is set the first time the logger is set.

MAINTENANCE

Upon final installation of the Series BDL Button Data Logger, no routine main­tenance is required.

Fast logging will considerably shorten the battery life. To preserve battery life,
it is recommended to use the longest practical sampling rate, and when the
logger is not in use, to set the sampling rate to the longest option.

A periodic check of system calibration is recommended. The Series BDL is
not field serviceable and should be returned if repair is needed (field repair
should not be attempted and may void warranty). Be sure to include a brief
description of the problem plus any relevant application notes. Contact cus­tomer service to receive a return goods authorization number before ship­ping.
