CheckSystem 2.3
Portable Test System
Consists of:
 Three phase, precision reference meter
with high accuracy in class 0.2
 Three phase current source in the range
1 mA ... 16 A
Application:
 Easy verification of meters under
precise load conditions, using the
built-in, compact, current source
 Automatic operation using predefined
load points without the need of an
external PC
 Display of vector diagram and phase
sequence for analysis of the supply
conditions
