The DMM is available with ADP5250/5470/5490 device.
The single button performs one measurement and the run/stop start continuous measurements.
The measurement mode can be selected between: Diode, Continuity, DC, AC voltage, DC, AC low current and DC, AC high current.
The range can be set to auto or manually specified.
For DC voltage the input impedance can be selected between 10MΩ and 10GΩ
Under options, the averaging time and the update rate can be set.
The history plot has a clear button, quick measurements and lets you specify the minimum and maximum number of steps. The scaling is by default automatic, but it lets you set manual offset and range under the plot options.
