Resets the display to the default values. (e.g. small fonts...).
10.2.4 :FETCh and :READ commands
These both commands are used to get measuring values from the instrument. With :FETCh
you get the values which are actually in the copied buffer for the interface. With :READ there
are internally two commands executed: :INITiate:IMMediate and :FETCh (see also 10.2.6.3,
‘:IMMediate INIM’ for further details).
If you request the same value twice with two :READ commands (e.g.
:READ:DC?;:READ:DC?) you get two different values of two different cycles. This can cause
problems for example with following request:
:READ:VOLTAGE:DC?;:READ:CURRENT:DC?
The two values you get for Udc and Idc are measured in different cycles!
