Pressing the NXT (F3) key will show the data point voltage and then mass velocity and then go to the
next data point. The number after Volt (i.e., Volt1) or Flo (i.e., Flo1) indicated the data point number.
The calibration table can hold up to 20 data pair points. Each data point has a voltage and mass
velocity associated with it.
K Factor
The K Factor allows the user to adjust the meter’s calibration. The ow meter increases the calculated
ow rate by the K Factor. This results in a direct scaling of the meter’s output across the entire full
range.
The K Factor parameter is accessed from the FLOW PARAMETER 2 menu by entering a Level 2
password “9111” and pressing the SPC key (F2).
F1 F2 F3 F4
The following screen will be displayed:
F1 F2 F3 F4
Press CHG (F1). Add the correction factor and press OK (F4).
If you want the ow meter to read 5% higher, enter 5.0%.
If you want the ow meter to read 5% lower, enter -5.0%.
If an existing K Factor is present, add the additional K Factor to the existing value.
Upon pressing OK (F4), an option to restore the database will follow.
Restore Database
In case of user error, the ability to restore the meter to the original factory settings can be achieved in
this menu. The display will show:
F1 F2 F3 F4
Press YES (F1) ONLY if you want to restore your database to the initial factory setting that the meter
was shipped with. All current user-entered settings will be overwritten. The green LP3 LED will ash at
a faster pace until the recall is performed. The "RESET CRC" screen will follow "RESTORE DATABASE".
Upon pressing NO (F4), an option to reset the NVRAM CRC will follow.
