4.2.24 Harmonic measurement characteristics
Measurement range in voltage
Per §4.2.2 and §4.2.3
Measurement range in current
Per §4.2.5 and §4.2.6
Range of use in harmonic
AC: harmonics of orders 1 to 25
AC+DC: all orders from 1 to 25, plus the DC
component
Frequency analysis band
- 0 to 25 times the fundamental frequency,
from among the network frequencies 50,
60, and 400Hz
- 0 to 12 times the fundamental frequency
of an 800Hz network
Stability of the current and voltage display ± (1% R ±2 pts)
Uncertainties on the RMS value of the
harmonic (zero corrected in A DC)
Level >10% and order <13: ±(5% R ±2 pts)
Level >10% and order >13: ±(10% R ±2 pts)
Level <10% and order <13: ±(10% R ±2 pts)
Level <10% and order >13: ±(15% R ±2 pts)
Note : - The display is "----" if the input signal is too low (U<8V or I<9A) or if the
frequency is less than 5Hz.
- Specific characteristics in MAX/MIN mode in THD
(from 10Hz to 1kHz):
•
Uncertainties: add 1% R to the values in the tables above.
•
Capture time of the extrema: approximately 100ms
