Understanding the Keys on the Control Unit
The following table provides general functional descriptions for the keys on the
control unit. Each key serves multiple functions. The current function of a key
depends on the current content displayed on the control unit screen.
Key Functional Description
ESC Turns off the control unit when held down for more than 2 seconds
Returns the menu to the previous level

Turns on the control unit when held down for at least 5 seconds
Displays the parameter settings from the top level
Displays subsettings of parameter settings (when applicable)
Displays current value/option setting corresponding to parameter setting selected
Activates editing mode for bracketed text/values ([xxx])
Deactivates editing mode for bracketed text/values (<xxx>) and saves text/values for
parameter

Calibrating the Sensor
Before taking velocity measurements, immerse the sensor into the flow to acclimate
the FlowShark HV’s integrated temperature sensor to the temperature of the flow.
Temperature differences between the sensor and flow can produce inaccurate velocity
measurements. A difference of only 1°C can lead to a measurement error of 0.24%.
Acclimation is complete when the temperature reading displayed begins to stabilize
and deviates only within a very limited temperature range of a few degrees.
Temperature and velocity stabilization may require 1 to 5 minutes upon initial use. It
can require several minutes if a large difference exists between the temperature of the
flow and the temperature at the location outside the flow.
