1. Introduction

The TFA device is a USB device, connected with a 2 m USB cable. The device will be

detected automatically by Windows® ME, Windows® 2000, Windows® XP und

Windows® .NET. Windows® 98 will ask some questions (see special chapter).(®

Microsoft Windows is a registered trademark of the Microsoft Corporation). The TFA

device would also operate with some versions of Linux.

No device driver are needed to operate the TFA device with Windows®. The already

installed standard USB drivers is sufficient. This protects the stability of the PC.

Depending of the configuration of the PC, more than 100 USB devices could be

connected. In case of Linux, only 16 TFA USB devices are supported.

Every TFA USB device has its own unique serial number. This makes it possible to

identify a certain device even the position in the USB hubs have changed. The serial

number could also be used by user programs so the device may be used as a simple

dongle.

The controlling of all TFA devices is done by the program „TFA USBTemp Control“.

This program will also do the visualization of the measured values and states. The

supplied software is described in the software manual.

Caution: It is strongly prohibited to use any of the TFA devices, if the failure of the

product may harm people. Usage in any medical applications is also prohibited.

2. USB-Temp

The housing of the sensor is made of black anodized aluminium. It is filled with casting

resin which complies with the best non-inflammability class V-O as per UL 94. The size

of the sensor is 25 mm x 15 mm x 40 mm. The USB cable is about 2 m long. The current

needed by this USB device is less than 20 mA.

To get the best results, the object to by measured should be placed at the position shown

above. The sensor is thermically connected with the aluminium housing so changes in

temperature will cause an immediate reaction.

The temperature is measured in steps of 0,0625° Celsius. The accuracy is at least +/-0.5°

Celsius. The sensor could be calibrated with the software “TFA USBTemp Control”.

Before delivery the USB-Temps are calibrated with an accuracy of 0,2° Celsius. The

operating temperature should be between -20° and +80° Celsius. Using it outside this

range may cause the destruction of the sensor. If temperature falls below 0° C the cable

must not be moved or bent.

The construction of the USB-Temp is very robust. Even hard conditions shown below do

not harm the sensor.

The casting resign protects the sensor against humidity. The sensor must not be located

under water for a long time, because the plastic may suck up water very slowly. There is

no warranty that the materials of the sensor will not react with components of wet or

aggressive environments. Attention for use inside aquariums.

The display of the measured values are done with the software “TFA USBTemp Control”.

This software could be configured to activate an alarm on several ways.

3. USB-Temp and USB-Battery

By USB-Temp recording of temperature values without PC is possible. This is done by

plugging the USB connector to the power supply USB-Battery. The sensor runs than with

battery power and is capable to record 4000 values. The values are stored permanently,

even if the sensor will be disconnected. They must be deleted explicitly by a command

from „TFA USBTemp Control“. The time slice between the measurements are also

defined in „TFA USBTemp Control“.

As shown on the picture, an USB-Battery could supply up to two devices with power.

After connecting the sensor, the USB-Battery will be turned on. The measurement will

start when pressing the right push button (see below). The start of the measuring will be

acknowledged with a short light on the LED. Then every taken value is signaled by

flashing the LED. If the LED is turned on constantly, an error was detected. The reason

for that is in most cases a full measuring buffer.

On the left side of the USB-Battery a battery low indicator and an power plug could be

found. The USB-Battery is delivered with an AC/AD adapter running at 230V.

1. Introduction

For operation of the TFA devices this Windows program is included in the distribution. It

allows a verysimple and easycontrollingof the devices.

2. TFA USBTemp Control

Every TFA USB device will be configured and controlled bythe application “TFA

USBTemp Control”. It will also do the visualization of values received from the devices.

The program window splits into two major windows. In the left tree based window the

connected devices and their properties are listed. The right data window displays

temperature curves.

User Manual Software “TFA USBTemp Control”

www.tfa-dostmann.de Page 4

The entries in the left state window could be as follows:

sensor name

•device type temperature sensor

•current temperature

•minimal detected temperature

•maximal detected temperature

•State of recorder

•switch points (if any)

•refresh interval

•version of the sensor

•serial number of the sensor

A double click on the current temperature causes an immediate call for new temperature

data no matter of the state of the refresh interval.

The recorded values can be stored for later displaywith the menu „File“->“save“ and

„save as“.

When movingthe cursor inside the data window the values next to the cursor position will

be displayed. This will help to get information about a specific time.

The time scale could be compressed or expanded with the menu point “View”-

>”increase/decrease view” or with the buttons .

The recorded values could also be printed. The print out will use the same time scale as

the data view.
