 This bench multimeter needs a very special procedure, to get the advantage of fast measurements.  This bench multimeter needs a very special procedure, to get the advantage of fast measurements.

 +This article should be applicable with minor adjustments for the all the new Siglent DMM's: SDM3045X, SDM3055, SDM3055A, SDM3065X

Zeile 12: Zeile 17:
 For both problems I gladly found the solution. The approach is like this: For both problems I gladly found the solution. The approach is like this:
   * set the sampling counter to MAX (600 Mio)   * 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'   * set trigger source to 'BUS'
   * initiate the DMM (arms the trigger)   * initiate the DMM (arms the trigger)
Zeile 18: Zeile 23:
   * read samples with ''R? 1''   * 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''.
  
 +==== Wrong User Manual ====
 +Due to false documentation in the //Siglent SDM3065X Remote Manual, Version RC06036-E01A, 2017// it was a hard way to find that solution.
