Thus the meter illustrated is showing the following readings: SWITCH  SETTING READING 1000 DC Volts 200 Volts DC 100 DC Volts 20 Volts DC 10 DC Volts 2 Volts DC 1 DC Volts 0.2 Volts DC 2 TS-352 B/U. Read the DC volts scale for the range at which the red lead is plugged. RANGE SCALE 50V 0-5 (and multiply by 10) 10V 0-10 (read the number on the scale) 2.5V 0-2.5 (read the number on the scale) Thus the meter illustrated is showing the following readings: RANGE 50V 10V 2.5V READING 20 volts DC 4 volts DC 1 volt DC (7) Using   the AC Volts scale. The AC Volts scale on the multimeter is used  to  measure  the  voltage  in  the  alternator-to-rectifier  circuit. Before  using  the  multimeter multimeter you have: to measure AC volts, do the   following steps for   the 2-15
