You're correct that most of the older analog VOM's and VTVM's do not measure AC amps (or power). But VOM is an abbreviation for Volt-Ohm-Milliammeter, although a few do go up to 10 amperes DC. But for measuring current in an AC circuit (saying or writing "AC Current" always bothered me), Simpson and a few other manufacturers made a clamp-on accessory that when plugged into a 260 in place of the normal leads, added that capability. And had the advantage over the standard clamp-on AC ammeter that the meter or indicator didn't have to be dangling on the wire that you were measuring. They also made a line splitter adapter widget that plugged into a wall outlet or extension cord. Then the device under test was plugged into the widget and the clamp-on accessory had individual access to either the line or the neutral going to the load.
