Final answer:
If the measurement across the solid-state relay terminals is normal but the load is not operating, there might be an issue with the load or its connection to the relay.
Step-by-step explanation:
If the measurement across the solid-state relay terminals is normal, but the load is not operating, it suggests that there may be an issue with the load itself or its connection to the relay. One possible problem could be a high resistance or an open circuit in the load. This could prevent the flow of current and cause the load to not operate. Another possibility is that the control signal to the relay is not being properly sent, which could be due to a faulty control circuit or a problem with the input signal.
