Model TDL-10 Portable Temperature Data Logger

Specifications - Installation and Operating Instructions

The Model TDL-10 is a compact and portable data logger used

for recording temperature of goods in-transit. It records a wide
temperature range from -4 to 158°F (-20 to 70°C). The data logger
features programmable high and low alarms that are indicated with
green and red LEDs on the face of the logger. The label on the
back of the logger allows for important shipping information to be
recorded. The TDL-10 can record over 8,000 measurements, and
the easy to use TDL-SC software makes retrieving data simple.
The TDL-10 can easily be started and stopped from a PC, delayed
to start up to thirty days in advance, or begin to start by a push of
a button.

2. Follow onscreen instructions.

CONNECT THE LOGGER

1. Remove the plastic piece from the bottom of the logger.

2. Place the logger on the blue outlined port.

3. Connect the TDL-SC Serial RS232 to the PC.

WAYS TO START LOGGING

Within the Start Device window, there are three ways that the data
logger can be set to start logging data. Select Start Device from
the Device menu to bring up this window.

START THE LOGGER

1. To start the logger, from the Communication menu select Auto
Configure Port.

2. From the Device menu select Start Device and choose the
desired Reading Rate, the preferred method for starting the logger,
and the alarm settings.

3. Click the Start button.

NOTICE

Starting the device erases all data currently stored in the logger.

By default, the logger is set to start logging by a manual start. To
start the logger manually, push the button that is recessed into the
face of the logger for three seconds when it is desired that the
logger start logging data.

To start automatically or start by a specified delay, choose one of
those options within the Start Device window.

ALARM SETUP

Within the Start Device window, click the Alarm Settings button.
Select Start Device from the Device menu to bring up this window.
Click the Change button and enter the desired information.

The LED will blink green when it’s in a non-alarm state, and once
the temperature has crossed an alarm threshold, it will blink red.

4. The logger will stop recording when the device is full or when
Stop Device is selected from the Device menu.

DOWNLOAD DATA

1. To download data, connect the logger to the PC.

2. Select Read Device Data from the Device menu.

3. Data is then presented graphically.

please consult the Software Manual.

BA TTERIES

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, select Stop
Device from the Device menu. Typical battery life is 90 days at
77°F (25°C) with a 5 minute reading rate.

MAINTENANCE

Upon final installation of the Model TDL-10 Data Logger , no routine
maintenance is required. The Model TDL-10 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.
