3 PRELIMINARY OPERATIONS:
3.1 Review and become familiar with the entire procedure before beginning the Calibration Process.
WARNING
Unless otherwise designated, and prior to beginning the Calibration Process,
ensure that all test equipment voltage and/or current outputs are set to zero (0)
or turned off, where applicable. Ensure that all equipment switches are set to
the proper position before making connections or applying power.
3.2 Connect the test equipment to appropriate power source. Set all POWER switches to ON and allow warm-up
as required by the manufacturer.
3.3 Throughout the Calibration Procedure, all hard keys will be in all CAPS, soft keys will be underlined,
submenus will be in Bold, and menu values will be in Italics.
3.4 Connect the TI Power Cord to appropriate power source. Press TI POWER key to on. Allow a 15 min
warm-up period.
3.5 Press the TI SETUP key, as necessary to display the SETUP menu, and press H/W TOOLS, DIAGS, SELF
TEST and RUN to initiate Self Test. When complete, ensure all Self-Tests pass. Press RETURN 3 times.
3.6 Press the TI SETUP key, as necessary to display the SETUP menu, and press STORE/RECALL. Press PREV
or NEXT, as necessary, to select PRESET SETTINGS and then press RECALL. Press RETURN.
3.7 Throughout the Calibration Procedure, when required to enter a value, utilize the ↑, ↓, ←and →keys to enter
the value.
3.8 TO 33K3-4-3457-1 was written for boot sw ver 1.00, main sw ver 1.01, 1.03 and 1.04, fpga ver 1.0 and cpld
ver 1.0. If the TI has another boot sw, main sw, fpga or cpld version, contact the TCM at AFMETCAL.
