-====== Meerstetter Temperature Controller ====== 
- 
-Refer to the **official documentation** of the Meerstetter for an **in-depth guide** to setting up and operating the system. The manual is very rigorous and covers everything required. This article just covers the main relevant points.

-===== Overview ===== 
- 
-==== Basic Concept ==== 
- 
-The Meerstetter temperature controller is used to stabilize objects to a given temperature. It measures the temperature of the object using a thermal resistor and adjusts the object temperature accordingly by driving a heating/cooling element connected to the object. 
- 
-==== Functionality ==== 
- 
-  * Temperature stabilisation to sub mK range 
-  * Exact control through software environment 
-  * Easy configuration using autotuning funtion 
-  * Custom programmable temperature ramps 
-  * Temperature monitoring and data logging 
-  * Programmable multi purpose pins for different applications 
-==== Hardware ==== 
-

- 
-X1: General connections 
- 
-  * power supply 
-  * multi purpose pins 
-  * serial connection 
- 
-X2: Connections for temperature measurement and control 
- 
-  * peltier element/heating foil etc. 
-  * temperature measurement 
- 
-X3: USB for connection to PC 
- 
-==== Software ==== 
- 
-Meerstetter provides a software for their temperature controller. This software is used to set up and monitor the temperature controller. It also provides a option for data logging. The newest version can be downloaded in the software section of the [[https://www.meerstetter.ch/de/products/tec-controllers/tec-1091|Official Website]]. 
- 
-===== Basic Setup ===== 
- 
-If you are setting up a Meerstetter temperature controller for the first time, refer to the {{ :groups:mg:meerstetter_temperature_controller_-_official_setup_guide.pdf |official setup guide}}. It takes you through all main steps and introduces you to the service software. The {{ :groups:mg:tec-family_user_manual_5134ad.pdf |Manual}} also covers this topic extensively. Refer to chapter 2. 
- 
-==== Power supply ==== 
- 
-The Meerstetter can operate in a voltage range of **5-24V DC** at a maximum current of **4A**. Connect the pins ''VIN'' and ''GND'' on X1 to a suitable lab power supply to power the meerstetter. The [[groups:mg:temperature_controller|current setup for the 1560 nm rio laser diode]] runs at **18V**. 
-==== Peltier Element/Heating Foil ==== 
- 
-The Meerstetter can run with a peltier element as well as a resistive heating element like a heating foil. The peltier element/resistive heater is connected to the pins ''OUT+'' and ''OUT-''. To use it correctly, you must configure the meerstetter accordingly using the [[groups:mg:meerstetter#software|service software]]. 
- 
- 
-==== Temperature Sensor ==== 
- 
-{{ :groups:mg:meerstetter_temperature_controller_-_temperature_sensor_connection.png?300|}} 
- 
-See page 4 of the {{ :groups:mg:project_ptb-cavity:tec-1091_datasheet_5175h.pdf |Datasheet}}. 
- 
-=== Object Temperature === 
- 
-The Meerstetter can do two-wire as well as [[wp>Four-terminal_sensing|four-wire measurement]]. For this the pins ''OBJ T° IA'', ''OBJ T° IB'', ''OBJ T° UA'' and ''OBJ T° UB'' on X2 are used. ''UA'' and ''UB'' for two wire, all four for four wire. Compatible temperature sensors are [[wp>Thermistor|NTC]], PT100 and PT1000. 
- 
-=== Sink Temperature === 
- 
-The Meerstetter can also monitor the temperature of itself. This is optional. The temperature sensor is connected to ''SINK T° A'' and ''SINK T° B'' on X2. For this an NTC is used. 
- 
-==== Software ==== 
- 
-The newest version can be downloaded in the software section of the [[https://www.meerstetter.ch/de/products/tec-controllers/tec-1091|Official Website]]. Refer to the documentation given there to get started. If you want to look something up, refer to the {{ :groups:mg:tec-family_user_manual_5134ad.pdf |Manual}} 
-===== Further Options ===== 
- 
-==== Status LEDs ==== 
- 
-To add a status LED to the Meerstetter, you can follow this step-by-step guide: 
- 
-  * connect its anode to any of the pins labelled "RES" using a resistor 
-  * connect its cathode to GND 
-  * connect the Meerstetter to your PC via a mini-USB B cable 
-  * connect a power supply 
-    * <fc #ff0000>!!!</fc> **ensure the Meerstetter is connected to a load, otherwise it might be damaged** 
-  * open the Meerstetter control software 
-  * make sure the Meerstetter is connected correctly and it says "ready" or "running" in the bottom left corner 
-  * type in "expert" at the bottom control panel and click the button labeled "login" 
-    * this makes the "Expert" tab show up at the top of the window 
-  * click on the tab labelled "Expert" 
-    * on the right side of the panel there are multiple selection fields labelled "RES1" to "RES8" 
-  * select the option you want to choose from the drop down menu corresponding to the pin the LED is connected to 
-    * <fc #ff0000>!!!</fc> Information on what these options exactly mean can be found on pages 47 and 48 of the {{ :groups:mg:tec-family_user_manual_5134ad.pdf | manual }} 
-  * write the settings to the Meerstetter using the button in the bottom right corner 
- 
-==== Smooth output current ==== 
- 
-As discussed as in this {{ :groups:mg:meerstetter_temperature_controller_-_mail_concerning_output_stabilisation.eml |Email}} from Klaus Zipfel to the Meerstetter engineering department, the output of the Meerstetter is not perfectly smooth. To stabilise the output current, this filter was designed. 
-

- 
-The capacitors used were the big red foil capacitors by Wima with a capacitance of ca. 10µF. The choke is a [[wp>Choke_(electronics)#Common-mode_(CM)_chokes|common mode choke]] with multiple tens of mH.
