4421A wattmeter stuck on connecting screen


If the 4421A is stuck on the connecting screen, first check that the cable and connectors are fitting properly. If possible, try testing the equipment with a different cable. Additionally, inspect the pins on the connectors to ensure none are bent or damaged. If the issue persists, and the 4421A device continues to display a "connecting" status after utilizing a different cable, please fill out a Return Merchandise Authorization (RMA) form. You can submit an RMA request through the provided link.
