press Time and turn the multi-function knob   or the inner knob of the 
navigation knob to adjust the time value at a relatively smaller step or turn 
the outer knob of the navigation knob to adjust the time value at a relatively 
larger step. The range available is from 10 ns to 1 s.  
 
Note: The larger the rotation amplitude of the outer knob of the navigation 
knob is, the faster the variation of the value will be. When you need to 
adjust the time value within a relatively larger range, this function can help 
you quickly finish the setting.

 or the inner knob of the navigation knob to adjust the time upper 
limit and lower limit at a relatively smaller step or turn the outer knob of the 
navigation knob to adjust the time upper limit and lower limit at a relatively 
larger step. The range of time upper limit is from 20 ns to 1 s. The range of 
the time lower limit is from 10 ns to 999 ms.  
 
Note: 
―  The time lower limit must be lower than the upper limit.  
―  The larger the rotation amplitude of the outer knob of the navigation 
knob is, the faster the variation of the value will be. When you need to 
adjust the time upper limit/lower limit within a relatively larger range, 
this function can help you quickly finish the setting.
