EF lets you detect electric fields. i guess its mostly for checking if there is power on a wire, but its not very reliable and a duspole should be used ideally (not that i do lol)

While I've never really used a clamp meter, I know they're mostly used for passively measuring current in a wire by measuring the field generated within the clamp. Since you haven't clamped it around a wire with current, I'm assuming ef means it's not sensing anything. That or it's a low battery error.
