Extech MA220 Features:

Auto/Manual Ranging The meter turns on in Autoranging mode. Press the RANGE button to enter manual ranging. Each press of the range button will step to the next range as indicated by the units and decimal point location. Press and hold the RANGE button for two seconds to return to Autoranging mode. Note: Manual ranging does not function in AC Current or Diode and Continuity check functions. In Temperature function, it will change the resolution from 0.1° to 1°.
