Which tool is used to test voltage at a valve solenoid?

A multimeter is a versatile tool commonly used for testing voltage, current, and resistance in electrical systems, including at a valve solenoid in irrigation systems. When measuring voltage, the multimeter can provide an accurate reading of the electrical potential at the solenoid terminals, which is crucial for diagnosing issues with the valve operation.

Using a multimeter allows technicians to determine if the solenoid is receiving the appropriate voltage to function correctly. If the voltage is too low, it may indicate a problem with the power supply or wiring. Conversely, if the voltage is as expected, but the valve still does not operate, it could suggest a malfunction within the solenoid itself.

In comparison, while a digital voltmeter is specifically designed to measure voltage, it lacks the additional capabilities a multimeter provides, which could be beneficial in diagnosing various issues. An oscilloscope, on the other hand, is more suited for observing waveform patterns rather than direct voltage measurements, making it less practical for this particular task. A clamp meter is primarily used for measuring current without interrupting the circuit and does not measure voltage directly.

Thus, the multimeter is the most appropriate and effective tool for assessing the voltage at a valve solenoid, helping technicians ensure that their irrigation systems are
