15) Press the [CALC COEF] key. All coefficients for the marked transducer will be
calculated, and those of the low range transducer will appear first on the LCD display.
16) Press [VIEW NEXT] to view the coefficients of the other transducer if desired.
17) To obtain a printout of the new coefficients, press [PRNT COEF].
18) To save the coefficients, press [SAVE QUIT]. The coefficients will be stored to non-
volatile memory. To abort the calibration without saving the coefficients just
calculated, press [EXIT QUIT]. The previous coefficients will be reinstated.
19) At the calibration menu, press [DONE]. Then press [DONE] at the next menu. The
system reinitializes and the Control/Display screen appears.
20) Repeat steps 9 thru 19 for the second pressure transducer.
21) Switch main console power to OFF.
22) Re-install the pressure transducers (0-50 PSIA transducer T2 is on top). Tighten all
connections 1/4 turn past finger tight.
23) Replace top left console panel. The system must not be operated unless all panels are
in place.
24) To print a calibration report, refer to section 4.2.5.
