2.7 MEASure Subsystem
2-15
This outputs presence/absence of measurement errors in an array. “True” is set to the
position where a measurement error occurs.
GW APS-1102 MEAS Curr Rat.vi
This returns the ratio (%) of the nth harmonic current to the fundamental current as 100%.
However, when in AC-INT mode, if the frequency is 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.)
<Input>
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>
Output [%]
This outputs the ratio of the harmonic current [%] 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.
Error
This outputs presence/absence of measurement errors in an array. “True” is set to the
position where a measurement error occurs.
GW APS-1102 MEAS Freq.vi
This returns the external sync signal frequency in Hz units.
The frequency measurement can only be performed in external synchronization mode (AC-SYNC or
AC+DC-SYNC). ([3, “Invalid in this mode”] error occurs.)
<Output>
Frequency
This outputs the external input signal frequency in Hz units.
Error
When a measurement error occurs, “True” is set.
GW APS-1102 MEAS Ac App.vi
This returns the apparent power in VA units.
<Output>
Apparent
This outputs the apparent power in VA units.
