Description of keys on the waveform display interface: 
Voltage/Current/Time: Adjust voltage/current/time base range 
Single: Single measurement key: when single measurement is enabled in the 
Stop status, the stop status is enabled again after one measurement based 
on the current data updating rate. When single measurement is enabled in 
the  Ready  status, the  instrument  immediately  restarts  one  measurement
