Description

Ohmmeter+ measures resistance, Ω, of a simple circuit connected through the headset port and converts to another unit by a user defined function, f(Ω). For example, Ω can be converted to Celsius by the Steinhart-Hart equation for a 10K thermistor:

0.001125308852122+0.000234711863267*ln(R)+0.000000085663516*ln(R)^3)^-1-273.15

The application is useful for measuring resistance and other units that change over time.
The application displays, records, graphs and emails spreadsheet data of simultaneous Ω and f(Ω) measurements.
