NOTE: If an accurate calibrated
container is not available an accurate
scale can be used to weigh the foam
concentrate pumped. The total volume
concentrates. DO NOT use water,
training or test foams for feedback
calibration verification.
Press the DISPLAY button. The control unit
display will show "A x.xx" for a single tank
system or dual tanks system with the
selector in Class A position or "B x.xx" for dual
tank system with the selector in Tank B
position, indicating the total volume of
foam concentrate pumped during the last
calibration run (See figure 3-8).
Set the bypass valve to the BYPASS position
and place a graduated measure container
at the outlet of the bypass hose that can
contain the expected volume of foam
concentrate, 5 gallons (19 liters) minimum
(figure 3-9).
