2.8 DISPlay Subsystem

GW APS-1102 DISP Mode.vi

This selects the measurement display selection. The measurement display selection setting is RMS

(RMS value), AVG (average DC), PEAK (peak value), and HC (harmonic current) 1 to 4. The relation

between the harmonic current mode and the harmonic degree is as follows.

HC1 (1st to 10th)

HC2 (11th to 20th)

HC3 (21st to 30th)

HC4 (31st to 40th)

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.)

When the measurement display selection is HC1 to HC4, the device cannot accept other commands.

([4, “Under Busy State”] error occurs.)
