AD7799 Internal Zero-Scale Calibration occurs without disconnecting pins

We have recently found that the AD7799 Internal Zero-Scale Calibration does not disconnect the outside circuit while it executes.  This wreaks havoc on our measurement.  Is there any work-around to this or must we choose a different part ?

 

PS: A system cal is impractical in our application.
