Figure 80. Offset Calibration Using Pulse Output

Step 1: Repeat Step 1 and Step 3 from the gain calibration to

configure the ADE7758 pulse output.

Step 2: Clear the xWATTOS and xVAROS registers.

Step3: Disable the Phase B and Phase C contribution to the APCF

and VARCF pulses. This is done by the TERMSEL[2:4] bits of

the COMPMODE register (0x16). Setting Bit 2 to Logic 1 and

Bit 3 and Bit 4 to Logic 0 allows only Phase A to be included in

the pulse outputs. Select Phase A, Phase B, or Phase C for a line

Step 4: Set the test system for I MIN , V NOM , and unity power factor.

For Step 6, set the test system for I MIN , V NOM , and zero-power

factor inductive.

Step 5: Measure the percent error in the pulse output, APCF or

VARCF, from the reference meter using Equation 49.

Step 6: Calculate xWATTOS using Equation 56 (for xVAROS

use Equation 57).
