6.4. LOCKDOWN
Due to the high square root gain associated with very low delta p values, the output is locked to zero
output value until the output value reaches the specified LockDown value entered. Above the
LockDown value the output is linear to air flow. The LockDown value can be changed from 0 to 20% of
Operating Range value. Lock-down values can be changed in 1% increments. The recommended
standard is 10%.

The Lockdown Delay menu allows the user to enter a lockdown time delay (0-10 seconds) that will
delay the display and output lockdown from occurring until the flow value or output value has remained
below the lockdown value for that duration.
