6.0 Interpreting results
The unit has an operating range of 0.50 mL/min to 500 mL/min (Figure
7). If the flow is less than 0.50 mL/min., the display will read “under range.”
If the flow exceeds 515 mL/min, the display will read “over range.” Exces-
sively high flow rates may damage this unit.
NOTE:
units of mL/min are equivalent to ccm.
6.1 Flow range display
The unit automatically adjusts the resolution of the display depending
on the flow range being measured. Table III shows the resolution of the
flow ranges.
