4.4.1 Span Sensor
->Span Sensor: High
Pressing ENTER causes the selection after 'Sensor:' to start flashing (Low / Mid / High). Then pressing UP or DOWN selects a different sensor. Note that the span value directly below will change according to which sensor is currently selected.
The high sensor covers ranges from 2 to 95% O2. Span gas that is near the top of this scale should be used to calibrate this sensor.
The medium sensor covers ranges from 200 ppm to 2% O2. Span gas that is near the top of this scale should be used to calibrate this sensor.
The low sensor covers ranges from 0 to 100 ppm O2. Span gas that is near the top of this scale should be used to calibrate this sensor.
4.4.2 Span Value
->Span 85%
Pressing ENTER causes the number after 'Span' to start flashing. The number has a range of 1 ppm to 100% and should be set equal to the concentration of the span gas used. This number corresponds to the sensor selected above. Pressing UP or DOWN adjusts the number.
4.4.3 Span Timer
->Span Timer: 7 min.
This function sets the hold time in span mode before the analyzer actually performs the span. Adjust to give enough time to purge with span gas.
