Climatic tests - DC calibrator M160
Kozárek, Radek ; Bartoň, Jan (referee) ; Šedivá, Soňa (advisor)
This bachelor's thesis is about climate test of DC calibrator M160. In section of theory, there are described standard. Next topic is calibrator M160 and its technical parameters, design of climate conditions. Next it deal with program Caliber, which automate measurement. Practical part of this thesis is about measurement of data in climatic conditions. This data were processed and compared with data, which guarantee manufacturer on reference range. In conclusion there is evaluation if this data could be used for whole operating temperature.

Automatic control of the high-resistance resistor decade in calibrator 9010
Bilík, Petr ; Sitta, Michal (referee) ; Šedivá, Soňa (advisor)
This bachelor thesis deals with automatic calibration of high-voltage resistence decade of calibrator 9010. The theoretical part deals with multifunctional calibrator 9010 developed by Meatest company, mainly with its high-voltage resistance decade. The other part of this work deals with Caliber. This is program for calibration of instruments. List of methods for determination of resistance decade and equations for device errors and uncertainty of measurement is included. The procedure of calibration high-voltage resistance decade is the result of the practical part. Output protocol from Caliber points to functionality of decade calibrator 9010.

Measurement of precise capacitance decade in environmental chamber
Schinneck, Jakub ; Bartoň, Jan (referee) ; Havlíková, Marie (advisor)
This bachelor’s thesis deals with the control capacitance decade in a climatic chamber. The theoretical part introduces a capacitance decade M525 of the MEATEST company and the program Caliber of the same company. It introduces the methods of capacitance measurement. In the bachelor’s thesis there is the calculation of the uncertainty of measuring devices. On the basis of the lowest uncertainty, we choose the most suitable measuring device. The practical part describes the measuring with the use of prepared procedure for verification of the capacitance of programmable decade. The last part contains the evaluation of the measurement results and their comparison with the manufacturer's specifications.

Automated calibration of instruments with PC
Obšilová, Lucie ; Kapinus, Tomáš (referee) ; Havlíková, Marie (advisor)
Bachelor´s thesis deals with the automated calibration of measuring instruments. Theoretical part presents the program Caliber and the most common communication interface. Practical part describes the creation of instrument cards and the calibration procedures to calibrate the power meter Chroma 66202 and the electronic load Chroma 63103A. In the next part of the thesis, there is the calculation of uncertainty for one calibration point of each calibration and the verification of the correctness of the program. The last part contains the evaluation of differences between performing the calibration using the program and manual execution.
