5.2 Simulation campaign

In following section recommended signal simulation is  described. Metrel PQA MI 2892
is  used  as  tested  instrument.  Refer  to  Power  Master  MI  2892  Instruction  manual  for
handling  measuring  site.  We  recommend  to  strictly  follow  the  guidelines  in  order  to
avoid  common  problems,  measurement  and  simulation  mistakes.  Figure  below  shortly
summarizes  recommended  simulation  practice.  Each  step  is  then  shortly  described  in
details.

Figure 62: Recommended simulation practice

5.2.1 Step 1: Connection setup

Preparation of Power Simulator/Calibrator CS 2890 and Power Master MI 2892 includes
the following steps:



Visually check both instruments and accessories.



Make sure, that Power Simulator/Calibrator CS 2890 is turned off.
