Harmonics/

Timeplot

Calculator

(continued)

Samples per

cycle

Select how many data points per cycle you wish to calculate.

Note that a high setting may cause calculations to take a long

time to complete. If the Harmonics/Timeplot Calculator is

processing slow, try decreasing this number.

Number of

harmonics to

calculate

Select how many harmonics you wish to calculate. The

maximum is the number of samples per cycle divided by two.

Note that a high setting may cause calculations to take a long

time to complete. If the Harmonics/Timeplot Calculator is

processing slow, try decreasing this number.

Harmonics in

THD

Select how many harmonics to use in THD calculations. As a

rule of thumb (and standards), you should use 40 harmonics for

50 Hz and 50 harmonics for 60 Hz.

If a parameter

is measured

Select if you wish to mix measured and calculated data, or

discard one or the other.

Selecting this option will cause the Harmonics/Timeplot

Calculator to skip calculation of channels that have been

measured.
