• In the expressions listed above, the unit of f is kilohertz.
• DC values of voltage and current are specied by Udc and Idc.
Frequencies other than DC are specied by U rms and I rms.
• When U or I is selected as the synchronization source, accuracy is specied for a source input of at least 5%
of range.
• The power phase angle is specied for a power factor of zero during 100% input.
• For current, active power, and power phase angle, add the current sensor accuracy to the accuracy gures
listed above.
• When 0.1 Hz ≤ f < 10 Hz, the accuracy gures for voltage, current, active power, and power phase angle are
values for reference purposes.
• When 10 Hz ≤ f < 16 Hz, the accuracy gures for voltage, active power, and power phase angle over 220 V
are values for reference purposes.
• When 30 kHz < f ≤ 100 kHz, the accuracy gures for voltage, active power, and power phase angle over 750 V
are reference values.
• When 100 kHz < f ≤ 1 MHz, the accuracy gures for voltage, active power, and power phase angle over
(22000 / f [kilohertz]) volts are values for reference purposes.
• For the 6 V range, add
±
0.02% of range to voltage and active power.
• When Probe 1 is used, add
±
0.02% of range to the voltage and active power for the 1/50 range of the sensor
rating.
• When Probe 2 is used, add
±
[(0.05% of reading) + (0.2% of range)] to the current and active power and add
±
0.2
°
to the voltage phase angle for 10 kHz or more.
• The valid measurement range of the 9272-05 is between 0.5 % of full scale and 100% of full scale.
• If the input magnitude is between 100% of range (exclusive) between 110% of range (inclusive), multiply the
range error by 1.1.
• Add
±
0.01% of range per degree centigrade to the voltage DC accuracy if a change in an ambient temperature
reaches
±
1
°
C or more after zero adjustment.
When Probe 1 is used, add
±
0.01% of range per degree centigrade to the DC accuracy of the current and
active power.
When Probe 2 is used, add
±
0.05% of range per degree centigrade to the DC accuracy of the current and
active power.
