Display resolution:
1 W
•
Measurement accuracy: at 45 Hz to 65 Hz
±
(2% of rdg +1 W)
at DC
±
(3% of rdg +12 W)
(at 23

5°C, load with the power factor 0.5 to lower than 1, 50 V or higher
output voltage, output current is 10% to 100% of the maximum output
current)
b) Apparent power
Calculated as output voltage RMS value × output current RMS value
