AVT5300 C

The ATmega88 microcontroller was used in the design of a miniature voltmeter with a versatile application. The system is equipped with a 4-digit LED display. The voltmeter has the functions of automatic change of measuring ranges. In addition, it has been equipped with the most typical (and needed) functions such as Hold or average.

The device is especially recommended as a panel meter; for power supplies, regulators and other devices

Selected parameters:

• DC voltage measurement 0-50V (only positive values)
• automatic change of ranges
• four measuring ranges: 0-1V, 1-5V, 5-10V, 10-50V
• measurement resolution depending on the range; 1,5,10 or 50mV
• input resistance 1Mom
• measurement of own voltages (common measuring and power mass)
• the ability to work as an ammeter up to 50A or a thermometer 0-150 deg
• various measurement functions: Hold, min, max, averaging
• range exceeded
• 6-15Vdc power supply
• set assembled and running
