AEDATS IV T53/T55/T63 ALIGNMENT WORKSHEET
(8) Fuel Flow T63 Flow Linearizer Programming
(a) Must load program on Laptop called "LinkHost"
(b) Enter Data from Calibration sheet (Compatible with Windows 98 or
older)
1 Open shortcut to Linear Link.
2 EDIT: Go to link setup. 0-10 V Out, RF Input and Top flow and Top Freq. From Cal Sheet.
3 EDIT: Header Fields enter Data from Calibration sheet.
(Enter)
4 VIEW: Mechanical Data
(Enter)
5 EDIT: Data fields enter 20 calibration points.
(Enter)
6 CONNECT INTERFACE CABLE TO LAPTOP AND LINEARIZER
8 VIEW: Open K Factor Plot
(Enter)
9 SHOULD SAY table generation successful.
(OK)
10 PROGRAM: Program Link
(OK)
11 Will download Data loaded from Calibration sheet
12 Enter low reading on voltage out
___________ (Enter)
13 Enter High reading on voltage out
___________ (Enter)
14 Verify Analog reading on voltage out ___________ (Enter)
15 Should Say Sending Table
16 Should read Calibration performed successful.
(9) Fuel flow measurement CEC 2700 BOX T63
(a) Ensure the system is in the T63 test mode, with the correct flight harness connected to the J-box.
(b) Set calculating counter controls as follows: (Channel 4)
1 DEC
6
2 C
01000
3 10n
0
4 Auto
depressed
5 X10
released
6 Sample Rate (fast)
1
7 Test
released
(c) Determine C settings for channel 4 Channel 4 C = (3600 x 8.337 x specific gravity) divided by the
turbine meter K-factor (Average from calibration sheet)
(d) Enter calculated value on channel 4 C switches
(e) At the Jbox on the fuel skid, Connect the Test Oscillator to TB 201 pins 1+ and 2-. Do not
connect to MT209 at the flowmeter.
The T63 flowmeter is a RF
carrier type signal. Frequency
will not read through the Linearizer system.
(NOTE: The frequency counter must have the low pass filter on)
(g) Enter Specific Gravity, K Factor and Temp in ADATS to read PPH from flowmeter Cal sheet.
(h) Enter Specific Gravity in ADATS under initialization (fuel correction factor) for PPH from
Calibration sheet. (Correction Factor:78 x 8.337 x SG / 2000)
(i) Connect Temp source to TC 208 to correspond to flowmeter Cal Temp.
(j) Set the following points with test oscillator:
1 1 V ac input
(k) oscillator frequency x c = PPH
(l) Enter S/G into ADATS to read PPH from Cal sheet
