Page 14: Applications
APPLICATIONS Electrical Connections The TMM-100 unit is supplied with cables and thermocouples to facilitate user connection to the various temperature sensors measured by the unit. The user is responsible for making the electrical connection between the unit and sensors according to the schematic shown in Figure 3-1. - Page 15 6944-1-ND] or equivalent, is a small chip that can be mounted to a printed circuit board near a heat source without impacting air flow. A Fan Control cable is also supplied with the TMM-100. Two alternative wiring configurations are shown in Figure 3-2. The relay load capability should be limited to <50V and <0.5A.
- Page 16 TTC-1002 0.5046ºC/mV The TMM-100 supplies 1mA to each of the diodes connected and measures the voltage for each of the diodes selected (see Figure 2-8). The diode voltage will decrease as the sensor heats up. The diode voltage value at equilibrium before heating occurs minus the diode volt- age at a specified time during the heating produces a voltage difference that is multiplied by the K Factor to produce a temperature difference.
- Page 17 TMM-100 APPLICATIONS 2) Connect up the power supply and measurement equipment shown in the Apparatus Setup. 3) Apply the 1.0mA Measurement Current to the diodes used for temperature measurement. 4) Wait for thermal equilibrium to occur - i.e., when the diode voltages stop changing - to re- cord the diode voltage.

TMM-100 INSTALLATION The software for installing and running the TMM-100 is supplied on a USB Flash Drive. The steps for installing the software on Windows 7.x or Windows 8.x operating system computer is de- scribed below. Step 1. Connect the supplied USB Ca- ble into the TMM-100 rear panel;... - Page 19 Step 8. With the installation complete, the last step is to create a desktop icon for easy ac- cess to the TMM-100 software. Follow the procedure normally used to create a desktop icon. The TMM-100 can now be connected to the computer. Plug the cable into a computer USB port and open the TMM-100 software.
