Two types of present values are displayed respectively at the upper and lower parts according to setting. Mode button Shifts from Measuring mode to each setting mode. The destination changes depending on how long the button is held down. Pressing Mode button for ≥ 2 seconds returns to Measuring mode from each setting mode.. Set button Shifts the setting value of each setting parameter item to a setting changeable state. When at setting changeable state, used to move through the digits of setting value and to enter (save) the setting value. Up button Shifts through setting parameter items and to increase or select the setting value. Down button Shifts through setting parameter items and to decrease or select the setting value.
