PRIMARY FLOW

The Primary Flow screen summarises the flow totals and provides options for their display on the
Flow Reading screen. To view the Primary Flow screen:
1. From the Main menu, use the Up and Down scroll keys to select Setup Instrument. Press the
ENTER Key. The Options screen is displayed.
2. Use the Up and Down scroll keys to select Primary Flow.. Press the ENTER Key.
The Primary Flow screen is displayed.
The screen displays the forward and reverse flow
totals: Fwd Total and Rev Total. If the totals need
to be adjusted, please refer to Section 3.5.2
"Resetting Totals", on page 29.
To change the display of forward and reverse totals
on the Flow Reading screen, select Display Total.
The options are: Both, None, Fwd Total and Rev
Total.
Damping Time and Damping Mode are duplicates of the setting found in the System menu (see
Section 4.6.5, "Adjusting the Damping Factor" on page 38).
Signal-loss Timeout is discussed on page 50. Once a signal has been acquired, it is deemed to
have been lost when the power and SNR ratio are insufficient for longer than the Signal Loss Time-
out setting.
Flow Direction allows you to reverse the sensor direction assignments. Changing flow direction
may result in a small difference in the magnitude of the reading observed (see section 4.6.2,
"Adjusting the Zero-Flow Offset (ZFO)" on page 34).
