 ===== SCPI and Fast Sampling =====
@@ Zeile 14: / Zeile 17: @@
 For both problems I gladly found the solution. The approach is like this:
   * set the sampling counter to MAX (600 Mio)
-  * clear the buffer with ''R?''
+  * clear the buffer with ''R?'' (to avoid getting an old value on the first reading)
   * set trigger source to 'BUS'
   * initiate the DMM (arms the trigger)
@@ Zeile 20: / Zeile 23: @@
   * read samples with ''R? 1''
+When the DMM isn't asked for any value, it will sample with the preset NPLC setting (200ms by default) and therefore also updates the LCD reading. \\
+If we want the latest value from the memory, we query for it with ''R? 1''.
 ===== Python Code =====
 Below you can find a python class for communicating with it. It implements the upper approach.
