Table 6-53:
The maximum recording
time depends on the
number of active channels
and the sampling
frequency
Accuracy of the sampling value:
• measurement ranges 600 V, 100 V, 10 V, 1 V:
± 0.2 % typical
± 0.5 % guaranteed
• measurement range 100 mV:
± 0.3 % typical
± 0.6 % guaranteed
The accuracy data are full scale errors.
6.11.9 Trend Recording
In Trend Recording Mode, you can make a historical plot of various
measurements over time. It is possible to measure RMS voltage, RMS
current, phase, real, apparent and reactive power and the power factor.
The main view has a CTS Chart. Each selected measurement function
appears in a separate diagram (i.e. all frequency measurements in the
frequency diagram). RMS current and voltage appear in separate diagrams.
Time is displayed in seconds on the x-axis. The diagram is scrolled from
right-to-left as new data is recorded.
