Sometimes receptacles aren't located for the ideal viewing angle.
I have receptacle type AC voltmeters that not only use one receptacle they hide the other receptacle. Duh?
Any meter should have a fuse. This morning, I had a coffeemaker malfunction and FLAMES shot up from the Formica and from the plastic coffeemaker. Genuine Mexican house. A single 30amp breaker protects the entire structure. Wooden house and 30 mph wind this morning. If I hadn't been there I would have returned to a charred crater. "CLICK! CLICK! CLICK!" then smoke and flames rolled out. I now have an 18" ceramic tile paying atop the 8" circular char on the counter top.
I have seen AC meters, especially the five-and-dime variety Chinese meters flame. It's ugly. A 1-amp fuse would protect an AC meter.
DROK® meters seem to be a cut above the rest. The cheap meters not only are inaccurate they have a sampling rate that is far too slow for me. A slow sampling rate makes the LED numbers seem to jump when voltage changes. My DROK meters have a separate + and - for the LED display. This allows for dimming if needed.
