4 — Viewing the secondary operating measured values — example
A table of the secondary operating measured values appears, as shown in Figure 3-9.
Since no measured AC currents or voltages are present at this time, all operating
measured values are close to zero. Deviations of the last digit are insignificant. The
measured values are automatically updated.
In the same manner, other measured and counter values can be read out.
