POWER FACTOR (PF)
range: -1.0 to +1.0
PF uncertainty can be calculated for any set value of output voltage, current and PF from following formula:
dPF = (1 – cos (ϕ+dϕ)/cos ϕ) * 100 [%]
where ϕ is set phase shift between voltage and current
dϕ is uncertainty of set phase shift form the above table
AC ENERGY uncertainty
It depends on set value of voltage, current, time and PF. The best uncertainty is 0.07% for apparent energy.
