4.4. FLOW ADJUST WIZARD [FAW]
EBTRON airflow measurement devices are factory calibrated to NIST traceable standards. Field adjustment
is not required when installed in accordance to published guidelines.
A flow adjust wizard is provided for installations where placement limitations warrant field adjustment of the
factory calibration. The wizard can be run with using a one-point (gain only) or two-point (gain and offset).
The FAW is not available for -B probe types set to convert airflow to pressure (DPCONVERT=YES).
 If minimum placement guidelines cannot be achieved, installed accuracy may be compromised.
Transmitters can be field adjusted to match a third-party measurement. Adjusted field measurements
typically result in comparative readings within ±3% of the third-party measurement. Be advised that
the third-party measurement may have uncertainties greater than or equal to ±10% and should only
be used to adjust the airflow measurement device if the probes do not meet minimum placement
requirements and the discrepancy is greater than the uncertainty of the third-party source.
 The factory default setting for the number of samples and units of measure can be modified via the
SETTINGS MENU under the TOOLS submenu. The factory default number of samples is set to 100
(30 seconds) and the default units of measure is set to CFM [L/s] (as long as a valid area is
provided).
 Increasing the number of samples may improve field adjustment in turbulent locations. Make sure
that the system is “locked” (i.e. fan speeds, dampers, terminals, etc. are not actively controlling) when
the FAW is run.
 The reference units of measure must be equal to the adjustment units of measure.
FAW (located in the TOOLS menu)
Use ↑↓ buttons to modify, {ENT} to accept and move to next prompt, {ESC} to move to previous prompt.
If the LOCK is enabled, pressing enter will indicate "CONFIG LOCKED" and this tool will not be available.
Navigate entire menu to step 11 to save settings. Press {ESC} at any time to exit without saving changes.
