2. Idle air control actuator - Wikipedia

   en.wikipedia.org/wiki/Idle_air_control_actuator

   An idle air control actuator or idle air control valve (IAC actuator/valve) is a device commonly used in fuel-injected vehicles to control the engine's idling rotational speed . [1] In carburetted vehicles a similar device known as an idle speed control actuator is used.

3. 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. Electrical isolation test - Wikipedia

   en.wikipedia.org/wiki/Electrical_isolation_test

   In electrical engineering, an electrical isolation test is a direct current (DC) or alternating current (AC) resistance test that is performed on sub-systems of an electronic system to verify that a specified level of isolation resistance is met. Isolation testing may also be conducted between one or more electrical circuits of the same ...

6. Tube tester - Wikipedia

   en.wikipedia.org/wiki/Tube_tester

   The simplest tester is the filament continuity tester, usually with a neon lamp connected in series with the filament/heater and a current limiting resistance fed directly by the mains. There is therefore no need to select the appropriate filament voltage for the particular tube under test, but this equipment will not identify tubes that may be ...

7. Electronic test equipment - Wikipedia

   Multimeter e.g., VOM (Volt-Ohm-Milliammeter) or DMM (Digital Multimeter) (Measures all of the above) LCR meter - inductance (L), capacitance (C) and resistance (R) meter (measure LCR values) The following are used for stimulus of the circuit under test: Power supplies; Signal generator; Digital pattern generator; Pulse generator

8. Solenoid voltmeter - Wikipedia

   en.wikipedia.org/wiki/Solenoid_voltmeter

   They can be used to test residual-current devices because the current drawn trips most RCDs when the solenoid voltmeter is connected between the live and earth conductors. Some manufacturers include a continuity test lamp function in a solenoid meter; these use the same probes as the voltage test function.

9. Battery indicator - Wikipedia

   en.wikipedia.org/wiki/Battery_indicator

   Some automobiles are fitted with a battery condition meter to monitor the starter battery. This meter is, essentially, a voltmeter but it may also be marked with coloured zones for easy visualization. Many newer cars no longer offer voltmeters or ammeters; instead, these vehicles typically have a light with the outline of an automotive battery ...
