Abstract: Paper summarizes individual parts of DMM (digital multimeter) and how they work. Design approach in comparison to commercial solution is in the thermal stabilization of the whole analog assembly. DMM has 8 custom designed PCBs (printed circuit board): Processor PCB, Keyboard and input backlit PCB, Analog PCB, Voltage reference PCB, Thermostat PCB, AC/DC PCB and LDO (Low dropout voltage regulator) PCB. User interface, program, thermal stabilization and mechanical construction are also described.
