Sample time
This screen allows the user to change the period over which the readings are averaged.
Use the
▲▼
buttons for coarse adjustment and the
◄►
buttons for fine adjustment. A typical setting would
be 3 seconds.
This value can be edited up to a maximum of 11 seconds and it represents the base time over which the
readings are taken for the rolling average system. A typical time of 3 seconds allows a large number of
readings to be taken before the mean calculation is made.
The averaging system continues to use 3 seconds of measured values, but on a rolling average basis.
Increasing the sample time will make the screen appear to update slower, but with a more stable reading.

Flow Alerts
Flow alerts can be switched between Enabled and Disabled. The alerts relate to the flow through the
selected valve. “High Flow” and “Low Flow” mean that the measured flow is outside the range normally
expected in the valve.
When working on unstable systems or systems that have little regulation, the alerts can sometimes
impede commissioning operations and, in these circumstances, they should be temporarily Disabled.
Back-Light Timer
The Back-Light Timer sets the period of time that the Back-Light remains on. Pressing any key will
reactivate it. Setting the light to a short time will preserve battery life.
Use the
▲▼
buttons to select an option, followed by the
button to accept it.
