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
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 AEDATS to read PPH from flowmeter Cal sheet.
(h) Enter Specific Gravity in AEDATS 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.
1 1 V ac input
(k) Oscillator frequency x c = PPH
