6.6.39 Voltage 2 Swell Level (V2Swell
LEVEL
) – Page 18, Address 51
Default = 0x7F FFFF
Voltage 2 Swell Level, V2Swell
LEVEL
, establishes a threshold at which a swell event is triggered.
This is a two's complement value in the range of -1.0
value1.0, with the binary point to the right of the MSB.
Negative values are not used.
6.6.40 Instantaneous Current 1 (I1) – Page 16, Address 2
Default = 0x00 0000
I1 contains instantaneous current measurements for current channel 1.
This is a two's complement value in the range of -1.0
value1.0, with the binary point to the right of the MSB.
6.6.41 Instantaneous Voltage 1 (V1) – Page 16, Address 3
Default = 0x00 0000
V1 contains instantaneous voltage measurements for voltage channel 1.
This is a two's complement value in the range of -1.0
value1.0, with the binary point to the right of the MSB.
6.6.42 Instantaneous Active Power 1 (P1) – Page 16, Address 4
Default = 0x00 0000
P1 contains instantaneous power measurements for current and voltage channels 1.
Values in registers I1 and V1 are multiplied to generate this value. This is a two's complement value in the
range of -1.0
value1.0, with the binary point to the right of the MSB.
6.6.43 Active Power 1 (P1
AVG
) – Page 16, Address 5
Default = 0x00 0000
Instantaneous power is averaged over each low-rate interval (SampleCount samples) and then added with
power offset (P1
OFF
) to compute active power (P1
AVG
).
This is a two's complement value in the range of -1.0
value1.0, with the binary point to the right of the MSB.
