from TRIG LEVEL A OUT to TRIG LEVEL B OUT (rear panel).
(6) Disconnect equipment setup.

12. Power Supply
NOTE
Do not perform power supply check if all other parameters are
within tolerance.
a. Performance Check
(1) Connect multimeter negative lead to TI GND L41 (fig. 1), and connect the
positive lead to the appropriate test point listed in table 7.
(2) Verify that the multimeter indicates within limits listed in table 7 for each of the
test points. If multimeter does not indicate within limits specified in table 7, perform
adjustments listed.

since they are based on the +5 V level.
b. Adjustments
(1) Connect multimeter negative lead to TI GND6 and connect the positive lead to
L10 (fig. 1).
(2) Adjust 5V adj (fig. 1) for 5.000 0.001 V indication on multimeters.
