The RANGE screen is as follows:
Range Select: Auto
Man Rng: R1
R1:
R2: 0- 1.00%

4.7.1Range Select
Range Select: Auto
Pressing ENTER causes the word Auto or Dgtl or Man to start flashing. Then pressing UP or DOWN cycles through the 3 words.
When Auto is selected, the analyzer will select the range automatically. The analyzer chooses the least range that will accommodate the current O2 concentration. The analyzer will switch to the next lower range (if available) when the concentration falls below 90% of the lower range setpoint and will switch to the next higher range (if available) when the concentration exceeds the range's setpoint.
When Man(ual), the analyzer will remain in the range specified in the 'Man Rng' field.
When Dgtl (Digital), the analyzer will select the range according to the signals on the remote digital cal contacts on the rear panel (and therefore disabling their original intent of being used aa remote calibration initiation inputs).
