However, all the items below apply to all tables.
• When the crest factor is set to 3
• When
λ (power factor) = 1
• Power figures that exceed 440 Hz are reference values.
• For nth order component input, add {n/(m+1)}/50% of (the nth order reading) to the n + mth order and n-mth
order of the voltage and current.
For the n+mth order and n-mth order of power, add {n/(m+1)/25} of the nth order reading.
• Add (n/500)% of reading to the nth component of the voltage and current, and add (n/250)% of reading to the
nth component of the power.
• Accuracy when the crest factor is 6: The same as when the range is doubled for crest factor 3.
• The accuracy guaranteed range by frequency and voltage/current is the same as the guaranteed range of
normal measurement. If the amplitude of the high frequency component is large, influence of approximately
1% may appear in certain orders. The influence depends on the size of the frequency component. Therefore, if
the frequency component is small with respect to the range rating, this does not cause a problem.

When the input signal levels are greater than or equal to 25
mV (current external sensor input) and the signal is greater
than or equal to 30% (0.1 Hz–440 Hz, frequency filter ON), of
the measurement range.
However, when the measuring frequency is smaller or equal
to 2 times of above lower frequency, the input signal is
greater than or equal to 50%.
Add 0.05% of reading when current external input is smaller
than or equal to 50 mV input signal level for each is double for
crest factor 6.
