Question

What is the purpose of testing actuators with a DMM?

1) To measure the voltage across the actuator
2) To check the continuity of the actuator
3) To verify the resistance of the actuator
4) To monitor the current flowing through the actuator

Answer 1

Testing actuators with a DMM serves multiple purposes like measuring voltage, checking continuity, verifying resistance, and monitoring current.

Step-by-step explanation:

Testing actuators with a DMM (Digital Multimeter) serves several purposes:

1. To measure the voltage across the actuator: By connecting the DMM in parallel to the actuator, you can determine the voltage being supplied to it.
2. To check the continuity of the actuator: By using the resistance measurement function of the DMM, you can verify if the actuator has a complete path for the current to flow through.
3. To verify the resistance of the actuator: Similar to checking continuity, the DMM can measure the resistance of the actuator, which can provide valuable information about its health and performance.
4. To monitor the current flowing through the actuator: By using the current measurement function of the DMM, you can observe the amount of current passing through the actuator, which can help diagnose any issues or abnormalities.
