Voltage, current and resistance ranges are usually set by turning a rotary range selection dial. This is set to the quantity being measured, e.g. AC volts, DC volts, Amps (current) or Ohms (resistance).
If the meter is non-auto-ranging, each function will have several ranges. So for example, the DC volts function range will have 1000V, 200V, 20V, 2V and 200mV ranges. Using the lowest range possible gives more significant figures in the reading.
