Figure 2-8: Meter with Calibration System
Figure 2-9 shows the screen on the controlling PC for a typical Demo Board. The error numbers are given in
percent. This means that for the measured Demo Board, the sum of all errors resulting from tolerances of PCB
components, current sensors, and 71M6543F tolerances was –3.41%, a range that can easily be compensated
by calibration.
Figure 2-10 shows a load-line obtained with a 71M6543F. As can be seen, dynamic ranges of 200:0.25, or
1:800 for current can easily be achieved. Dynamic current ranges of 2,000:1 (0.1 A to 200 A) have been
achieved with 50 μ ? shunts mounted in ANSI enclosures.
