m. Multimeter will indicate between 1.700 and 1.650 V dc, if not adjust R21 (fig. 17) (R).
n. Perform (1) through (11) below:
(1) Set ON-OFF switch to OFF.
(2) Remove multimeter connections.
(3) Remove jumper wire connection from TI chassis and A/D 1A2A8 GROUNDING
STRAP (fig. 15).
(4) Remove electrical shunt from connector on A/D 1A2A8 circuit board JP2 (fig. 16)
and install electrical shunt to a single pin on JP2.
(5) Remove A/D 1A2A8 circuit board from extender card (LPFT-1048).
(6) Remove extender card (LPTF-1048) from TI.
(7) Reinstall A/D 1A2A8 circuit board in TI.
(8) Reinstall A/D 1A2A8 circuit board GROUNDING STRAP (fig. 15) to chassis.
(9) Remove MODULE SIMULATOR from TI optical module compartment (fig. 15).
(10) Replace TI top cover assembly.
(11) Reinstall optical module into TI optical module compartment.
11. Installation and Use of Software Level 1.08a
NOTE
The following steps install software level 1.08a into system
software of TI. This software is used to alter start time, in
nanoseconds, of data collect cycle, causing TI optical trace to
move left or right on crt. This will cause change to distance
reading.
NOTE
When software level 1.08a is used to change distance
parameters (ZERO-KM SETTING) of an optical module for a
given wavelength, that particular optical module must remain
with TI mainframe for calibration to remain valid.
CAUTION
Never connect/disconnect keyboard or external disk drive to TI
with power on or damage may occur to TI.
a. Perform setup steps (1) through (4) below:
(1) Place TI ON/OFF switch to OFF.
(2) Connect keyboard cable to KEY BD connector located on rear of TI.
(3) Connect external disk drive cable to EXT.DSK connector located on rear of TI.
(4) Place TI ON/OFF switch to ON.
b. To install software level 1.08a, perform steps (1) through (22) below:
