12.6 Executing the Measurement of dmax Caused by Manual Switching
• Initializing the Measurement of dmax Caused by Manual Switching
• The initialization takes approximately 30 s.
• Rms voltage Un and voltage frequency Freq are updated every 2 s while the
initialization is in progress in the same manner as when the voltage fluctuation and
flicker measurement is reset.
• Keep the voltage of the power supply to be measured in steady-state condition
while the initialization is in progress.
• Rated Voltage Un and Voltage Frequency Freq
• If the assignment method of rated voltage is auto, the rms voltage at the start of the
first measurement is used as rated voltage Un. The measured data is calculated
with respect to rated voltage Un.
• If the assignment method of rated voltage is Set, the rated voltage setting is
displayed as Un(Set).
• Rated voltage Un and voltage frequency Freq are fixed to the first measured values
after the measurement of dmax caused by manual switching is started and are not
updated.
• Switching the Element for Displaying the Measurement Data
You can select the element from below. The selectable items vary depending on the
installed elements.
Element1, Element2, Element3, and Element4
Note
If an element that is not being measured is assigned to a display target element, <OFF> is
displayed by the element number, and all measured data and judgement are displayed as
blank.
• Resetting the Measurement of dmax Caused by Manual Switching
To initialize and restart the measurement, execute reset after the measurement of
dmax caused by manual switching is complete and the flicker measurement status is
indicating Complete. You cannot initialize or start the measurement in the Complete
status.
Reset the measurement of dmax caused by manual switching to change the following
settings.
• Measurement conditions (chapter 4 in the User's Manual IM WT3001E-01EN)
• Measurement conditions of the measurement of dmax caused by manual switching
