DESCRIPTION
The TMM-100 is designed to simplify the
gathering of temperature data from eight
Thermal Test Chip diode temperature sen-
sors. The system contains precision current
sources for supplying diode measurement
current (IM), voltmeter capability for diode
measurement (VM), and Type-T thermocouple and 10KΩ NTC thermistor measurement ca-
pability for monitoring the environment temperature. Front-panel mounted connectors pro-
vides for up to eight temperature sensing diodes, two thermocouples and two thermistors. All
temperature sensor channels can individually be enabled or disabled using simple com-
mands.
For any of the selected eight diode temperature sensing channels, the internal precision IM
current source provides 1.00mA with a voltage compliance of 2V. The internal voltage meas-
urement circuit measures to 1.999V with 1mV resolution. The temperature measurement
resolution of 0.1C for all sensors provides for accurate temperature differential measure-
ments.
The TMM is powered through its USB connection to a computer, so no external power supply
is required.
FEATURES
Self-contained for easy setup and operation
8 diode voltage measurement channel circuitry
Diode channels use 1.0mA current source.
2 Integrated Type-T thermocouple measurement circuitry
2 10KOhm NTC thermistors measurement circuitry

TMM-100 OPERATION
TEA
2-1
Once the TMM-100.exe file
has been started, the Opening
Screen shown in Figure 1 will
appear.
TMM-100_User_Manual_r4.doc Rev4
If the TMM-100 unit is already
connected to the computer,
the green indicator to the right
of the COM port box (near top
right of the screen) will turn
green and the connected COM
port number will appear in the
port box.
If the TMM-100 unit is not
plugged into the computer, the
indicator next to the COM port
box will be red and a message
box (see Figure 2-2) will ap-
pear. Plug the unit’s USB into
the correct computer port, wait
about 10 seconds, and then
click on the Retry button. After
a few more seconds, the con-
nection indicator will turn
green and the COM port ac-
tually used will appear in the
COM port box.

TMM-100 OPERATION
TEA

The TMM-100 Operating
Screen is divided into several
sections:
TMM-100_User_Manual_r4.doc Rev4
Communications Status
Located in the top right (see
Figure 2-1). This section con-
tains the COM port box and
COM port status indicator.
Immediately below are the
status indicators for data
READ and SCAN.
Sensor Selection
Down the left center are the
selection check boxes for Di-
ode Temperature Sensors
numbered 1 through 8. At the
bottom of the diode selection
is a slide to select between di-
ode readings in millivolts and
degrees centigrade.
Immediately below the unit
model number and name are
the Thermistor Sensor selec-
tion check boxes.
Figure 2-3 Sensor Selection
Under the Communications Status section is the Thermocouple Sensor selection check
boxes.
The data will only be read for those sensors that have check marks in their boxes, as shown
in Figure 2-3.
Sensor Read Control
Located in the center right portion of the screen, this second deals with the actual collection
sensor reading collection.
Clicking on the READ button, will cause a single data reading for each selected sensor. The
collected readings will appear in the data box to the right of the individual sensors.
If a sensor is not selected, its data box will contain a “0”, as shown in Figure 2-4.
TMM-100 OPERATION
TEA
TMM-100_User_Manual_r4.doc Rev4 2-3
The Diode Temperature Sensor data
is in terms of millivolts (mV) or de-
grees centigrade (ºC), as determined
by the slide control below the diode
selection column. In order for the di-
ode results to be in centigrade, the
diode voltage must be correlated to
temperature by clicking on the
CALIBRATE DIODES button near
the QUIT button at the bottom right
of the screen. The calibration proce-
dure is described below.
The data for both the Thermistor and
the Thermocouple Sensor is in terms
of ºC.
The CONTINOUS READ button is a
toggle type which is either OFF, as
shown in Figure 2-4 as a grey but-
ton, or ON, as shown in Figure 2-5
as a green button. Clicking on the
button will change the operational
state.
Figure 2-4 Sensor Read
Clicking on the CONTINOUS READ
button will cause the data for all the
selected sensors to be updated
every 100ms.
Figure 2-5 CONTINUOUS READ button
Fan State
Immediately to the right of the SENSOR READ CONTROL section is the FAN STATE sec-
tion. As shown in Figure 2-6, the but-
ton in this section toggles between
FAN OFF and FAN ON states. A relay
connection on the module’s rear panel
allows either for direct control of a
power supply for powering (≤50V, ≤0.75A) a measurement system fan or for providing a digi-
tal signal for fan control circuitry or other measurement environmental system.

Timed Scan Control
This section is dedicated to the
controls required for collecting data
at a fixed sample rate over some
period of time. Clicking on the
START SCAN button begins the
collection of data from all the se-
lected sensors. When clicked, the
grey START SCAN turns into the
yellow ABORT SCAN button caus-
ing the scan operation to cease.
Figure 2-7 Time Scan Controls
In the top middle of the section is the control for setting the maximum time period from 1 sec-
ond to 10,000 seconds in steps of 1 second. The Max Time in seconds can be set by either
using the up/down arrows on the left of the time set box or by actually entering the max time
in the box. To the right of the setting box is an Elapsed Time indicator box to show where
within the max time the current data scan is.
The Sample Rate selection control has three fixed rates – 10ms, 100ms, and 1s – that can be
selected by clicking the up/down arrow on the left of the data box. The 10ms selection only
works when a single sensor (i.e.,either Diode, Thermistor, or Thermocouple) is selected. The
100ms and 1s selections will work for any combination of selected sensors.
Immediately below the Sample Rate control is the entry box for the datafile path and file-
name.
If the TMM-100 is running on a Windows XP Pro computer, then the full path and filename
must be entered here in order to save the data file.
If the TMM-100 is running on a Windows 7.X, 8.1 or 10 computer, then clicking on the
folder button to the right of the filename area brings up the Windows Save As dialog box
that allows for setting the path but the filename still have to be entered.
If the box is checked for Add .xls extension, then the datafile will be saved with the .xls
suffix. Otherwise, the filename is saved as a text file.
The Notes area is designed to accept up to 4 lines of entered alphanumeric information that
can be use to describe the measurement run operating conditions, information about meas-
urement samples, or other information.
The data, with Notes can be saved after collection by clicking the SAVE DATA button.
