  • 1. Embedded PIC Microcontroller Based Digital Power Multimeter This Digital Power Multimeter is designed to display the all electrical and Electronics parameters in one single equipment. The Digital Power multimeter is fully integrated without having any transducers or converters externally. It is a microcontroller based circuit designed with powerful software builtin for the following sampling inputs for the measurement of several AC Parameters, DC Parameters and Others. This can be installed in a test bench of the equipment under test. Application: • Multimeter Monitoring Parameter: o AC Voltage & Current o DC voltage & Current o Resistor s ohms o Diode drop voltage o Temperature sensor using Temp Degree
