USB miltimeter with microprocessor
Samek, Martin ; Kolka, Zdeněk (referee) ; Kovář, Jan (advisor)
Topic of my terminal labour is a proposion of multimeter and its resulting connection by the help of bus USB. When proposing the multimeter there was a tendency to use a minimal number of component parts to conserve a good protection against a bad usage in application. The most widespread busbar USB is used for connection of the multimeter and a computer. Standard HID is used for communication, for that it is not neccessary to install any system drivers.

Uncertainty and Compatibility in Measurement
Kvapil, Josef ; Zavřel, Jiří (referee) ; Havlíková, Marie (advisor)
This work is concerning the matter of resistor and inductance measurement uncertainty. It addresses the elaboration of general measurement uncertainty processes for the measurements mentioned above using Agilent 4263B, Tesla BM507 and Tesla BM591 measurement instruments. This bachelor’s thesis describes possible sources of measurement uncertainty that might arise from the use of these measurement instruments. It also describes practical examples of resistivity and induction standard measurement projects using these measurement instruments followed by a compatibility evaluation of these measurements.

Measuring and recordes electrical electrical quantities
Vít, Tomáš ; Čejka, Miloslav (referee) ; Havlíková, Marie (advisor)
The aim of this Bachelor's thesis is the design and realisation of a device able to measure and record electrical quantities - voltage, current and resistance. The part of design is a theoretical description of measurement methods with the selection of suitable components. Based on these components is designed hardware design of the device, followed by its practical assembly. The final device is able to be measured electric variables at centain intervals, which are then stored on the SD card. The final element is the CSV file containing the measured data and time of each measurement.

Construction and Realisation of 4 1/2 Decimal Order Panel Meter with Integrating A/D Converter
VOBR, Jiří
The work deals with construction and realization of 4 {$^1\!/\!_2$} decimal order panel meter, with application for measaurement of the resistance. The work is focused on the theory of integrating converter especially on dual-slope-integrating principle and its application in measuring process. Furthermore the work deals with method of four wire resistance measurement of small resistance and specific realization of the measuring system.The work includes the calibration and the accuracy testing measurements.
