EFW Using User Programmable Table Measurements
If it is desired to use User Programmable Table measurements
in the calculation and reporting of EFW, perform the following
steps:
System Setup
1. Create the desired User Programmable Tables as
described on
14–80 .
2. Assign the User Table measurement to the proper
Measurement Mode Menu as described on
14–88 .
3. Assign the User Programmable Table measurement to
the desired Report Page as described on
14–77.
Calculating EFW
4. Perform the measurements used in the calculation of
EFW.
For example, if Tokyo method is selected in the OB
Report Format, found in System Parameters page 2,
EFW is calculated by measuring BPD, FL, APTDxTTD.
If user programmable tables are used in the
measurement of BPD, FL and/or APTDxTTD, these
measurements should be performed first prior to the
factory default measurements [i.e. FL (user1), BPD, FL,
APTDxTTD].
After all measurements have been completed, EFW is not
displayed in the measurements results area, but is displayed on
the Report Page.
If it is desired to use User Programmable Table measurements
in the calculation of EFW, it would be helpful to program a User
Measurement Sequence as described on
14–84 .
If measurement averaging is active, EFW will be calculated
from the average of similar factory default and user
programmable table measurements.
