7. Select the current Min-Max-value from the pull-down list. This is an independent
setting for averaging period just for current. You will use the effects of this
setting later during the analysis of the data when you choose to see the voltage at
the time max current happened.
8. If you are using Flexi-Set current probes, you have a choice of sensitivity ranges.
Select the one you want from the pull-down list.
9. (Optional) Choose Measure or Calculate to determine how PQ Log will derive
the data it displays for neutral current. Sometimes it is useful to choose Calculate
even if the neutral current probe is connected around the neutral feeder. This is
the case when you want to measure power the same way a revenue power meter
does it, if the power meter uses a calculated neutral.
10. Click OK and you are back to the Setup for Logger function P menu. Select the
Averaging Period from the pull-down list. Notice how different settings affect the
available logging time. If you select 1 s, the available logging time is shortest,
but you get the most detailed data. Choose the setting that is required for the
power quality standards you want your data to comply with, or the one that gives
you the most detailed data for the time period of your logging session.
11. Select whether you want the Logger to quit logging when its memory is full
(Linear), or keep logging continuously by overwriting the oldest data with new
data (Circular).
12. (Optional) Choose the averaging period for min/max power measurements from
the pull-down list.
13. Select how you want to control the start and stop times of the logging session:
