If you have a newer generation 900-268 (with 
the  USB  icon  on  the  cover)  this  can  be  used 
as  a  900-213,  meaning  you  can  tether  the 
probes  directly  to  the  computer  using  the 
900-268. To engage operation in this fashion, 
press 3 times on the panel key. Repeating this 
operation will return the unit to WiFi mode.
