DRIFTCAL HANDLER
Option (cont.)
The Set Max Total Drift option:
The Set Max Total Drift? option is used to specify the maximum
allowable total calibration drift, as a percentage of the full-scale
reading (25% of F.S. is the default value). If a calibration results in a
total drift greater than the value specified, an error condition occurs.
To use this option, proceed as follows:
Note:
If the XMO2 displays a value greater than 25% of F.S. after
reaching equilibrium, change the maximum total drift value to
50% before calibrating the unit.
You may now do one of the following:
•
Press
[N]
as many times as necessary to select another DriftCal
Handler menu option. Then, press [Y] and proceed to the
appropriate section of this chapter for instructions.
•
Press
[N]
until you reach the Done? option of the DriftCal Handler
menu, then press [Y] to return to the Calibrate System menu.
The Set Max Drift/Cal option:
The Set Max Drift/Cal? option is used to specify the maximum
allowable drift per calibration, as a percentage of the full-scale
reading (10% of F.S. is the default value). If a calibration results in a
drift change greater than the value specified, an error condition
occurs. To use this option, proceed as follows:
Note:
If the XMO2 displays a value greater than 10% of F.S. after
reaching equilibrium, change the maximum Drift/Cal value to
25% before calibrating the unit.
