Chauvin Arnoux F405 - Harmonic Distortion (THD) Characteristics

45
4.2.19.2 Characteristics in current
Measurement range (1)
5.0 Hz to 999,9 Hz
1000 Hz to 1999 Hz
Specified measurement
range
1 to 100% of the
measurement range
0 to 100% of the
measurement range
Uncertainties
± (0.4% R + 1 pt)
Resolution
0.1Hz
1Hz
Note (1) - If the level of the signal is too low (U<3V or I<3A) or if the frequency is
less than 5Hz, the device cannot determine the frequency and displays
dashes "----".
Specific characteristics in MAX/MIN mode (from 10Hz to 5kHz in voltage and
from 10Hz to 1kHz in current):
• Uncertainties: add 1% R to the values of the table above.
• Capture time of the extrema: approximately 100ms.
4.2.20 Characteristics in THDr
Measurement range
0.0 – 100%
Specified measurement range
0 to 100% of the measurement range
Uncertainties
± (5% R ±2 pts) in voltage
± (5% R ±5 pts) in current
Resolution
0.1%
4.2.21 Characteristics in THDf
Measurement range
0.0 – 1000%
Specified measurement range
0 to 100% of the measurement range
Uncertainties
± (5% R ±2 pts) in voltage
± (5% R ±5 pts) in current
Resolution
0.1%
 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
