To select the desired option press ATC until the option is displayed on the LCD. If temperature compensation is active, measurements are compensated using the temperature coefficient (default value 1.90 %/°C). To change the temperature coefficient, enter the setup mode and select the “tc” item (See SETUP for details, page 14). -
