•As often as necessary
This means if you do an analysis and your result is outside the proper operating range, then you need to increase the frequency of analysis.
If your result is out of range you should have analyzed sooner
•Increase the frequency so that all corrections are made while still within operating range
•Better to do analysis and scheduled maintenance on an amp-hour basis instead of by the calendar
When Calculating to Make Adjustments
•First make sure that it’s necessary. Did you do the analysis correctly?
•Don’t round-off numbers until your final result.
•Check your math, it’s easier than trying to “fix” your bath because you’ve made an error in calculation.
