21. Programming Flowmeter Data in AEDATS II/IV
a. Performance Check
correspond with each target frequency shown in the table below. For each run chosen, the Flowmeter
Hz value should be as close as possible to the Target Frequency Hz value. Use the five flowmeter
data runs to complete the columns labeled "Flowmeter Hz" and "Flowmeter PPH" of the table below.
Repeat this step for all three flowmeters listed in the table.
(2) Calculate the average K-factor for each selected set of five runs. Record the average K-factors, the
sampling temperatures, and specific gravity values from the flowmeter calibration sheet.

NOTE
The following Step (3) must be performed for each of the three flowmeters
in the table above.
(3) AEDATS II
(4) Enter Specific Gravity, Temperature, and Average K factor from the flowmeter calibration sheet into
AEDATS II. Follow the instructions below.
(a) In AEDATS go to MAIN MENU. Select "M" for MAINTENANCE UTILITIES.
(b) Select "C" for CALIBRATION MENU.
(c) Select "S" for SETTINGS MENU.
(d) Enter Specific Gravity in selection "1" (Fuel Specific Gravity) of Cell Constants screen.
(e) Enter Sampling Temp. in selection "2" (Fuel Sample Temperature) of Cell Constants screen.
(f) Enter flowmeter K-factor in selection "3", "4", or"5" of Cell Constants screen as follows:
1 * Enter "3" (Low K-Factor) for the T53/T55/T64 Fuel Flowmeter.
2 * Enter "4" (Mid K-Factor) for the T53/T63 Oil Flowmeter.
3 * Enter "5" (High K-Factor) for the T700 Fuel Flowmeter.
(5) AEDATS IV
Enter Specific Gravity, Temperature, and Average K factor from the flowmeter calibration sheet into
AEDATS IV. Follow the instructions in accordance with AEDATS IV, Automated Engine Data
Acquisition Test System Manual; H355-7, Test Cell Instrumentation Package (TCIP), Appendix A,
Pages A7 A22.
