2. Push (Correct Digitally) to access the
connection correction screen. This screen allows you
to virtually swap phases and invert the current inputs
instead of a manual correction.
3. If the Logger is able to determine a better phase map
or polarity, push (Auto Correct) to apply the new
settings.
Auto Correct is not available if the algorithm is not able
to detect a better phase map or when no errors are
detected.
Note
It is impossible to detect all incorrect hook-ups
automatically. You must verify the suggested
modifications carefully before you apply the digital
correction. Applications with single-phase energy
generation can deliver the wrong results when you
apply the Auto Correct feature.
The algorithm works in a way that creates in three phase
systems a sequence with a clockwise phase rotation.
Power
– In the Power mode you can get the values and a
live trend chart for each phase (A, B, C or L1, L2, L3) and
total as:
• Active Power (P) in W
• Apparent Power (S) in VA
• Non-active Power (D) in var
• Power Factor (PF)
Use (Fundamental/RMS) to toggle between full
bandwidth power values and power of the fundamental.
In the fundamental power screen you see these values:
• Fundamental Active Power (P
fund
+) in W
• Fundamental Apparent Power (S
fund
) in VA
• Fundamental Reactive Power (Q
fund
) in var
• Displacement Power Factor (DPF) / cosϕ
Push (Show Menu) to open a list of simplified Power
screens that show all phases and total of one parameter,
all parameters of one phase, or total.
