Null computing will be an option operation, could be setup in accordance with user 
demand. If user does not implement Null computing, this parameter is not   
required, direct implementation of the next step. 
(To  know  the  specific  setting  methods  of  the  Null  value  setting,  please  refer  to 
Chapter 2 “To Set Up Measurement Parameters”, Null computing)

Use the history function to review or save the data that has acquired by the current 
measurement  function.  The  data  can  be  display  “Info”  (information),  “List”  and 
“HistoG” formats. 
Press Update softkey to update the History data. 
Press Save softkey to save data. 
NOTE 
When measuring small value resistance, Null operation will be recommended, the
