Description
Kh = VMAX * IMAX *47.1132 / ( In_8 * WRATE *N ACC *X) Wh/pulse. The default
value results in a Kh of 1.0Wh/pulse when 2520 samples are taken in each
accumulation interval (and VMAX =600, IMAX = 208, In_8 = 1, X = 6).
The maximum value for WRATE is 2 15 – 1.
WRATE controls the number of pulses that are generated per measured Wh quantities. The lower WRATE is the slower the
pulse rate for measured energy quantity. The metering constant Kh is derived from WRATE as the amount of energy measured
for each pulse. That is, if Kh = 1Wh/pulse, a power applied to the meter of 120V and 30A results in one pulse per second. If
the load is 240V at 150A, ten pulses per second will be generated. X is controlled by the PULSE_FAST and PULSE_SLOW bits
in the CECONFIG register.
The maximum pulse rate is 7.5kHz. The maximum time jitter is 67μs and is independent of the number of pulses measured.
Thus, if the pulse generator is monitored for 1 second, the peak jitter is 67ppm. After 10 seconds, the peak jitter is 6.7ppm.
The average jitter is always zero. If it is attempted to drive either pulse generator faster than its maximum rate, it will simply
output at its maximum rate without exhibiting any rollover characteristics. The actual pulse rate, using WSUM as an example,
is:
RATE =
WRATE ? WSUM ? F S ? X
2 46
Hz ,
where F S = sampling frequency (2520.6Hz), X = Pulse speed factor

Description
These constants control the gain of their respective channels. The nominal
value for each parameter is 2 14 = 16384. The gain of each channel is directly
proportional to its CAL parameter. Thus, if the gain of a channel is 1% slow,
CAL should be scaled by 1/(1 – 0.01).
These two constants control the CT phase compensation. No compensation
(lag) is introduced. Range: ± 2
