5.1.1 Rotary knob position:
Test functions are selected by turning the rotary knob from the OFF position to the desired function. The display will show the initial
screen for that function.
Press a black keypad button to change the test mode from the standard measurement, or to select the Backlight and Buzzer ON/OFF.
The rotary knob should always be returned to the OFF position after use. Do not rely on the AUTO OFF function as this unnecessarily
wastes battery life.
