2. Solenoid voltmeter - Wikipedia

   en.wikipedia.org/wiki/Solenoid_voltmeter

   Solenoid voltmeters are useless on low-voltage circuits (for example, 12 volt circuits). The basic range of the voltmeter starts at around 90V (AC or DC). Solenoid voltmeters are not precise. For example, there would be no reliably perceptible difference in the reading between 220 VAC and 240 VAC. They are meant for intermittent operation.

3. Multimeter - Wikipedia

   en.wikipedia.org/wiki/Multimeter

   A multimeter (also known as a volt-ohm-milliammeter, volt-ohmmeter or VOM) [1] is a measuring instrument that can measure multiple electrical properties. [ 2 ] [ 3 ] A typical multimeter can measure voltage , resistance , and current , [ 4 ] in which case can be used as a voltmeter , ohmmeter , and ammeter .

4. Test light - Wikipedia

   en.wikipedia.org/wiki/Test_light

   A test light, test lamp, voltage tester, or mains tester is a piece of electronic test equipment used to determine the presence of electricity in a piece of equipment under test. A test light is simpler and less costly than a measuring instrument such as a multimeter , and often suffices for checking for the presence of voltage on a conductor.

6. Avometer - Wikipedia

   en.wikipedia.org/wiki/Avometer

   The original AVOmeter was designed to measure direct current (3 ranges, 0.12, 1.2 & 12 A), direct voltage (3 ranges, 12, 120 & 600 V) and resistance (single range, 0 - 10,000 ohms, 225 ohms mid-scale). All ranges could be selected by a single rotary switch which set both the function and the range value.

   Left to right: AA, AAA, AAAA, N (E90) and A23 batteries An open A23 battery showing the LR932 cells with an intact battery. The A23 battery (also referred to as 23AE, GP23A, V23GA, [1] LRV08, [2] 8LR932, [3] 8LR23, MN21, L1028 or ANSI-1181A) is a dry battery consisting of eight LR932 cells, with a nominal voltage of 12 V.
