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.

Often the value or type designation of the component is given on the diagram beside the part, but detailed specifications would go on the parts list. Detailed rules for reference designations are provided in the International standard IEC 61346.

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.
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.
The solenoid can be useful for positioning, stopping mid-stroke, or for low velocity actuation; especially in a closed loop control system. A uni-directional solenoid would actuate against an opposing force or a dual solenoid system would be self cycling. The proportional concept is more fully described in SAE publication 860759 (1986).
