A solenoid voltmeter is a specific type of voltmeter electricians use to test electrical power circuits. [1] It uses a solenoid coil to attract a spring-loaded plunger; the movement of the plunger is calibrated in terms of approximate voltage. It is more rugged than a D'arsonval movement, but neither as sensitive nor as precise.

Keysight commercial digital voltmeter checking a prototype. The following items are used for basic measurement of voltages, currents, and components in the circuit under test. Voltmeter (Measures voltage) Ohmmeter (Measures resistance) Ammeter, e.g. Galvanometer or Milliammeter (Measures current)
A variable force solenoid (VFS) is an electro-hydraulic device that controls pressure proportionally or inversely proportionally to a signal (voltage or current) obtained from the on-board controller of a powertrain. A low flow VFS is used as a signal level devices for transmission line pressure control or application of clutches.
A voltmeter is an instrument used for measuring electric potential difference between two points in an electric circuit. It is connected in parallel . It usually has a high resistance so that it takes negligible current from the circuit.

Entry-level cable testers are essentially continuity testers.. A continuity tester is an item of electrical test equipment used to determine if an electrical path can be established between two points; [1] that is if an electrical circuit can be made.
Neon test lamp for line voltages Non-Contact AC Voltage Detector. 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.
