You will notice from the previous five examples that the average and
maximum flow rate can be expressed in any units, i.e. mgd, gpm, cfs, etc.
However, express the average and maximum flow rate in the same units for
any given situation.
3.2.4 Sample Volume x 25 Milliliters
To take a 25 mL sample every time a sample is initiated, set the Sample
Volume x 25 thumbwheel switch to 01. To take a 50 mL sample each time a
sample is initiated, set the Sample Volume x 25 thumbwheel switch to 02.
Refer to Table 9 for more examples.
