GW APS-1102 MEAS Curr Res.vi
This resets the stored output current peak value (hold) to 0 Apk.
GW APS-1102 MEAS Curr Ave.vi
This returns the output current average value (AC+DC average value) in A units.
Average
This outputs the output current average value (AC+DC average value).
Error
When a measurement error occurs, “True” is set.
GW APS-1102 MEAS Curr Cres.vi
This returns the output current crest factor.
The crest factor is calculated as “current peak value/current RMS value”.
Average
This outputs the crest factor (peak-to-rms ratio) of output current.
Error
When a measurement error occurs, “True” is set.
GW APS-1102 MEAS Curr Harm.vi
This returns the harmonic current [Arms] in the specified degree range.
However, when in ACT-INT mode, if the frequency neither 50 Hz nor 60 Hz, the harmonic current
cannot be measured. ([3, “Invalid in this mode”] or [6, “Invalid in this frequency”] error occurs.)
Parameter
This specifies the order range to be outputted. Any of 1 (1st to 10th)/2 (11th to 20th)/3 (21st
to 30th)/4 (31st to 40th) can be specified. The default setting is “1”.
Output [Arms]
This outputs the harmonic current [Arms] in the specified order range in an array. When the
order range specified in Parameter is “1”, 1st, 2nd, … 10th are output from the top.
