Page 4: Foreword
Paragraphs preceeded by this symbol explain hazards that could damage the instrument and the connected equipment or may cause loss of data. Note This manual also contains "NOTES" and "HINTS" written in this form. Please read this advice carefully! © 2018 Thorlabs GmbH...
Page 5: General Information
MTD Series TEC controller can be evaluated and adapted to a particu- lar thermal load. The MTDEVAL1 is powered by any stabilized 12 V / min. 2.3 A DC power supply. The links to the MTD Series Data Sheets can be found in section Documentation Reference.

Windows 8.1 (32-bit, 64-bit) · ® Windows 10 (32-bit, 64-bit) For operation of the MTDEVAL1, the Microsoft .NET Framework V 4.5.1 or later is required. This software (V 4.6.1) is included with the MTDEVAL1 installation package. © 2018 Thorlabs GmbH...
Page 8: Getting Started
MTDEVAL1 2 Getting Started For proper operation of the MTDEVAL1, please observe the order of the following steps: 1. Install the software to your computer. 2. Install the daughter board (MTD415LE or MTD415TE) or the MTD1020x to the MTDEVAL1. 3. Connect the TEC and the temperature sensor.
Page 9: Operating Principle
The parameters in the volatile memory are only used during a single operating session. This memory is cleared upon power-down. When the MTDEVAL1 is powered up, the data from the flash memory are read out to the volat- ile memory.
Page 10: Operating Elements
TEC element. Power Supply Connection The MTDEVAL1 consumes up to 2.3 A, depending on the TEC current. Connect any external DC power supply that delivers (11.5 ... 13.0) V DC and at least 2.3 A to the terminal (1). Take care for correct polarity.
Page 11: Installing Software
5 Installing Software 5 Installing Software The MTDEVAL1 control software can be downloaded from our web site https://www.thorlabs.com/software_pages/ViewSoftwarePage.cfm?Code=MTDEVAL. Note It is strongly recommended that all applications open on the PC are exited prior to starting the software installation! Note Unzip the downloaded package and execute the setup.exe that can be found in unzipped folder: If no .NET Framework is installed or a version older than V 4.5.1 is detected on the computer,...
Page 13 5 Installing Software If you are prompted to reboot the computer, please do so. Note The reboot is required to ensure a proper operation of the MTDEVAL1! After rebooting, the installer automatically resumes installation: Click 'Next >' to continue. Click 'I accept...' if you do so, then 'Next >' to continue.

Page 17: Preparation
6 Preparation Note Do not connect the MTDEVAL1 to a PC prior to installing the software! This may lead to corrupt installation of the driver software. 1. Install the daughter board with MTD415LE or MTD415TE, or the MTD1020T in the appro- priate socket on the MTDEVAL1.

GUI and saves them to a file. In other words, this function does not read the actual parameters from the MTDEVAL1! Load Settings from File loads the information from the selected file to the GUI. In this case, the GUI content is compared to the content of the volatile memory of the MTD module and dif- fering parameters are highlighted.
Page 29 This way, all changed parameters become active and will be saved permanently. 2. Click to one of the highlighted parameters and press the Enter key. This way, all changed parameters become active, but they are not stored to the flash. © 2018 Thorlabs GmbH...
Page 30: Oscillation Test
P share is changed, the set temperature needs to be changed for a small amount in order the trigger the loop. Below an example experiment is described in detail: · After enabling the TEC with initial setting, the temperature is settling: P=1000; T=25.0°C © 2018 Thorlabs GmbH...
Page 31 Lower P to 5000 mA/K; decrease the set temperature to 25.0 °C - the loop still oscillates: P=5000; T=25.0 °C · Lower P to 3000 mA/K; increase the set temperature to 25.1 °C - the loop still oscillates: P=3000; T=25.1 °C © 2018 Thorlabs GmbH...
Page 32 Increase P to 2600 mA/K; increase the set temperature to 25.1 °C - the loop oscillations are still damped: P=2600; T=25.1 °C · Increase P to 2800 mA/K; decrease the set temperature to 25.0 °C - the loop oscillates again: P=2800; T=25.0 °C © 2018 Thorlabs GmbH...
Page 33 In other words, the duration of 1 period is ~ 5.085 s. 6. Enter these values in the GUI. Pressing the Enter key triggers the calculation of the PID shares and the cycle time by the firmware and immediately displays the calculated loop parameters: © 2018 Thorlabs GmbH...
Page 34 The optimized PID parameters are valid for a steady state that depends on the set tempera- ture as well as on the ambient conditions (ambient temperature, temperature of the thermally controlled object). Any changes of the operating and/or environmental conditions may re- quire a re-adjustment of the PID parameters. © 2018 Thorlabs GmbH...
