A digital multimeter is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms). ... Digital multimeters combine the testing capabilities of single-task meters—the voltmeter (for measuring volts), ammeter (amps) and ohmmeter (ohms).

Multiple sets of measurement information can simultaneously be displayed at the same time. Logging function with Trend Capture is an essential tool for documenting the performance of your designs, processes or systems, or unattended monitoring while working on other projects. It plots measurements as a single line to help detect signal anomalies over time. Using onboard Trend Capture can graphically view logged readings without a PC. (Software and interface cable optional). Log multiple sessions or log data continuously for over 200 hours.

The Compact true-RMS meter for field service technicians. The Fluke 115 is the solution for a wide variety of electrical and electronic testing applications. It has some key features like Large white LED backlight to work in poorly lit areas, Resistance and continuity, Min/Max/Average to record signal fluctuations, and CAT III 600V safety rated.
