Measurement accuracy For more information about the measurement accuracy for input from external current
sensors, see "Measurement accuracy" (p.152).
• Values for f.s. depend on measurement ranges.
• “F” in the tables refers to the frequency in kHz.
• When using the 1 mA/ 2 mA range
Add ±1 A to 0.1 Hz to 100 kHz measurement accuracy for current.
Add (±1 A) × (voltage read value) to 0.1 Hz to 100 kHz measurement accuracy for
active power.
• When using the 200 mA/ 500 mA/ 1 A/ 2 A/ 5 A/ 10 A/ 20 A range
Add ±1 mA to DC measurement accuracy for current.
Add (±1 mA) × (voltage read value) to DC measurement accuracy for active power.
• When using the 1 mA/ 2 mA/ 5 mA/ 10 mA/ 20 mA/ 50 mA/ 100 mA range
Add ±10 A to DC measurement accuracy for current.
Add (±10 A) × (voltage read value) to DC measurement accuracy for active power.
• When using the 200 mA/ 500 mA/ 1 A/ 2 A/ 5 A/ 10 A/ 20 A range
Add ±(0.02×F)% rdg. to the measurement accuracy for current and active power for
which (10 kHz < f  100 kHz).
• The following input are considered reference values:
Values for voltage, current, and active power for which 0.1 Hz  f < 10 Hz.
Values for voltage, current, and active power in excess of 220 V or 20 A for which
10 Hz  f < 16 Hz.
Values for current and active power in excess of 20 A for which 500 Hz < f  50 kHz.
Values for current and active power in excess of 10 A for which 50 kHz < f  100 kHz.
Values for voltage and active power in excess of 750 V for which 30 kHz < f  100 kHz.
