2. Kill A Watt - Wikipedia

   en.wikipedia.org/wiki/Kill_A_Watt

   The Tweet-a-watt [13] is a hacked version of the standard Kill-A-Watt Plug in Power Meter. By piggybacking on the device's on-board LM2902N op-amp chip, the creator was able to get readings for voltage and current and transmit to a computer, which then sent this to Twitter via handle @tweetawatt.

3. Wattmeter - Wikipedia

   en.wikipedia.org/wiki/Wattmeter

   The wattmeter is an instrument for measuring the electric active power (or the average of the rate of flow of electrical energy) in watts of any given circuit. Electromagnetic wattmeters are used for measurement of utility frequency and audio frequency power; other types are required for radio frequency measurements.

4. Multimeter - Wikipedia

   en.wikipedia.org/wiki/Multimeter

   Any meter will load the circuit under test to some extent. For example, a multimeter using a moving coil movement with full-scale deflection current of 50 microamps (μA), the highest sensitivity commonly available, must draw at least 50 μA from the circuit under test for the meter to reach the top end of its scale. This may load a high ...

5. Electronic test equipment - Wikipedia

   en.wikipedia.org/wiki/Electronic_test_equipment

   Electronic test equipment is used to create signals and capture responses from electronic devices under test (DUTs). In this way, the proper operation of the DUT can be proven or faults in the device can be traced. Use of electronic test equipment is essential to any serious work on electronics systems.

6. Smart meter - Wikipedia

9. Current clamp - Wikipedia

   en.wikipedia.org/wiki/Current_clamp

   An electrical meter with integral AC current clamp is known as a clamp meter, clamp-on ammeter, tong tester, or colloquially as an amp clamp. A clamp meter measures the vector sum of the currents flowing in all the conductors passing through the probe, which depends on the phase relationship of the currents. Only one conductor is normally ...
