The value to be used for QUANT can be determined by the following formula:
V ? I
QUANT _ W = ?
error
100
VMAX ? IMAX ? LSB
LSB = QUANT LSB value = 7.4162*10 W
Where error = observed error at a given voltage (V) and current (I),
VMAX = voltage scaling factor, as described in section 1.8
IMAX = current scaling factor, as described in section 1.8
-10
Example: Assuming an observed error as in Figure 2-5, we determine the error at 1A to be +1%. If VMAX is
600V and IMAX = 208A, and if the measurement was taken at 240V, we determine QUANT as follows:
240 ? 1
QUANT _ W = ?
1
100
600 ? 208 ? 7 . 4162 ? 10 ? 10
= ? 11339
QUANT_W is to be written to the CE location 0x2F. It does not matter which current value is chosen as long
as the corresponding error value is significant (5% error at 0.2A used in the above equation will produce the
same result for QUANT_W ).
Input noise and truncation can cause similar errors in the VAR calculation that can be eliminated using the
QUANT_VAR variable. QUANT_VAR is determined using the same formula as QUANT_W .
