The meter for the margin supply was reading about 15% high. I wanted to open it and replace the scale resistor but it's closed by the silver metal band crimped around the edge of the meter. Trying to remove it would make a horrible mess. Instead I added an external resistor to fix the scaling shown in the next picture.
