CE Calibration Parameters
The table below lists the parameters that are typically entered to effect calibration of meter accuracy.

Description
0x08
CAL_IA
16384
These constants control the gain of their respective channels. The nominal
value for each parameters 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).

PHADJ_A
0
These two constants control the CT phase compensation. No compensation
occurs when PHADJ_X = 0. As PHADJ_X is increased, more compensation
(lag) is introduced. Range:
±215 – 1. If it is desired to delay the current by the

QUANTA
0
This parameter is added to the Watt calculation for element 0 to compensate
for input noise and truncation.
LSB = (VMAX*IMAX / In_8) *7.4162*10
-10 W
0x18
QUANTB
0
This parameter is added to the Watt calculation for element 1 to compensate
for input noise and truncation. Same LSB as QUANTA.
0x15
QUANT_VARA
0
This parameter is added to the VAR calculation for element A to compensate
for input noise and truncation.
LSB = (VMAX*IMAX / In_8) * 7.4162*10
-10 W
0x1B
QUANT_VARB
0
This parameter is added to the VAR calculation for element B to compensate
for input noise and truncation. Same LSB as for QUANT_VARA.
0x16
QUANT_I
0
This parameter is added to compensate for input noise and truncation in the
squaring calculations for I
2. QUANT_I affects only I0SQSUM and I1SQSUM.
LSB = (IMAX
2/In_82)*7.4162*10-10 A2
