• Stored as an integer with 0.1 resolution. (Multiply % by 10 to get the integer,
divide integer by 10 to get %. For example, 94.9% = 949.)
NOTES:
• The Full Scale is the "nominal" value for each of the different types of readings. To
compute the Full Scale, use the following formulas:
Current [CT Numerator] x [CT Multiplier]
Voltage [PT Numerator] x [PT Multiplier]
Power 3-Phase (WYE) [CT Numerator] x [CT Multiplier] x [PT Numera-
tor] x [PT Multiplier] x 3
Power 3-Phase (Delta) [CT Numerator] x [CT Multiplier] x [PT Numera-
tor] x [PT Multiplier] x 3 x sqrt(3)
Power Single Phase (WYE) [CT Numerator] x [CT Multiplier] x [PT Numera-
tor] x [PT Multiplier]
Power Single Phase (Delta) [CT Numerator] x [CT Multiplier] x [PT Numera-
tor] x [PT Multiplier] x sqrt(3)
Frequency (Calibrated at 60 Hz) 60
Frequency (Calibrated at 50 Hz) 50
Power Factor 1.0
THD, Harmonics 100.0%
Angles 180°
• To interpret a limit alarm fully, you need both the start and end record (for dura-
tion).
• There are a few special conditions related to limits:
• When the meter powers up, it detects limits from scratch. This means that
multiple "out of limit" records can be in sequence with no "into limit" records.
Cross- reference the System Events for Power Up events.
• This also means that if a limit is "out," and it goes back in during the
power off condition, no "into limit" record will be recorded.
