easier reading. The resolution affects only the data displayed, not the resolution of data
measured and stored.
If this temperature is exceeded the measurement session is suspended and the system
displays a HOT alarm message. The system resumes when the temperature drops to
90% of the specified temperature. It is recommended to Enable this feature to maximize
sensor life and system performance.

Description
Check this box to enable the user measurement offset option. If checked enter an
offset value or a target value:
Enter an offset value to manually adjust the measurement value. If the gas unit type
or gas unit (defined in the Measurement configuration screen) are changed the
offset value is automatically reset to zero.
This field cannot be updated. It shows the current measurement value with the offset
applied.
Enter a target measurement value. The offset value is automatically computed so the
displayed measurement value will be equal to the target value.
Select this button to recompute the offset value at any time during the measurement
process. The offset value will be computed based on the current and target
measurement values.
Check this box to enable the out of range protection (recommended). When enabled
and the measured value exceeds the instrument specification, the measurement
interval will be increased to 1 minute to protect the lifetime of the sensor spot. If
disabled, the lifetime of the spot can be negatively impacted if the sensor is exposed
to high oxygen concentrations for long periods of time.
