The PDA²-430 is a hand held, battery and/or DC input powered DMM. It combines useful power supply and multi-meter functions into one unit. The functions selected were ones that could be the most useful during the development and debug of electronic control based systems. The user interface and LCD provide an easy to use menu driven interface to control the power supply and DMM functions. The power supply is digitally programmable from 0 to 30 Volts in 0.5 Volt increments. This range satisfies the voltage requirements of many devices like breadboard circuits, circuit board assemblies, sensors, etc. The DMM functions consist of a continuity tester and a logic probe. The continuity tester provides basic point to point testing for verifying device nets like PCB board traces and Cable/harness assemblies. The logic probe verifies voltage levels greater than or equal to logic levels and can even detect switching at lower frequencies.
