Watts Accuracy
Specification: 0.2% of r 0.1% of range, +4mW + (0.05/PF * F)% of reading
Note: F is the frequency of measurement in kHz
Reading = 240W
Range = Volts range * Amps range = 215V * 6.25A = 1343.75W
Frequency = 0.06kHz
Power Factor = 0.8
Accuracy = 0.2% of 240W + 0.1% of 1343.75W + 4mW + (0.05 / 0.8 * 0.06)% of 240W
= 480mW + 1343.75mW + 4mW + 9mW
= 1.837W or 0.77% of signal.
