5.3 Measurement specifications

Measurement accuracy
• Values for f.s. depend on measurement ranges.
• “F” in the tables refers to the frequency in kHz.
• 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 200 mA or 500 mA range, add ±0.1% rdg. to current and active
power for which 1 kHz < f ≤ 10 kHz.
• Values for voltage, current, and active power for which 0.1 Hz ≤ f < 10 Hz are for ref-
erence only.
• Values for voltage, current, and active power in excess of 220 V or 20 A for which 10
Hz ≤ f < 16 Hz are for reference only.
• Values for current and active power in excess of 20 A for which 500 Hz < f ≤ 50 kHz
are for reference only.
• Values for current and active power in excess of 15 A for which 50 kHz < f ≤ 100 kHz
are for reference only.
• Values for voltage and active power in excess of 750 V for which 30 kHz < f ≤ 100
kHz are for reference only.
Effective measuring range Voltage: 1% to 130% of range (1,000 V range, up to 1,000 V)
Current: 1% to 130% of range
Active power: 0% to 169% of range (when using 1,000 V range, up to 130%)
However, defined when voltage and current fall within the effective measurement range.
Other parameters: Valid within the voltage, current, and active power effective mea-
surement range.
