How to Use the TM-100
Equipment Setup
1) Insert the DIN8 connector of the TM-100 temperature sensor into a DIN8
extension cable.
2) Insert the other end of the DIN8 extension cable into a DIN8 transducer input
on an iWorx data acquisition unit or amplifier.
Start the Software
1) Open LabScribe by clicking on the LabScribe desktop icon.
2) When the program opens, select Preferences from the Edit menu (or from
the LabScribe menu on a Macintosh computer).
3) Select the Channel preferences dialog window. Name the channel to which
the TM-100 is connected. Set the Mode/Function for this channel to DIN8.
Also, set the sampling rate and display time. Click OK.
Calibration of the TM-100 Temperature Sensor
1) Prepare two beakers of water, one at 10
o
C, and the other at 40
o
C. Measure
the temperature of the cold water with a thermometer just before the TM-100
temperature sensor is placed in the beaker.
2) Place the tip of the TM-100 temperature sensor in the center of the beaker of
cold water.
3) Click the Start button on the Main window of the LabScribe software and
begin recording. Type “Calibration at <Cold Water Temperature>” on the
comment line to the right of the Mark button.
4) After about twenty seconds in the cold water, the output of the TM-100
temperature sensor displayed on the recording channel should reach a stable
level. Press the Enter key on the keyboard to mark the recording. Continue
recording.
5) Measure the temperature of the warm water with a thermometer just before the
TM-100 temperature sensor is placed in the beaker. Type “Calibration at
<Warm Water Temperature>” on the comment line.
6) Continue recording as the temperature sensor is moved from the cold water to
the warm water.
7) After about twenty seconds in the warm water, the output of the TM-100
temperature sensor displayed on the recording channel should reach a stable
level. Press the Enter key on the keyboard to mark the recording. Click Stop
to halt the recording.
8) Select Save As in the File menu, and type a name for the file. Choose a
destination on the computer in which to save the file. Click on Save to save
the file.
